15 May 2008: Funny Symbols in Web Pages I see funny symbols in the text on some web pages, particularly where I'd expect to see hyphens or apostrophes. What's wrong? You're viewing the site with the wrong code page. The code page is the assortment of characters your browser uses to render text, and it must match the code page that was used to create the site. Usually your browser picks the correct one automatically, but if you've previously changed the code page (or if another web site switched code pages on you), or if the web site doesn't specify the correct code page, the site won't display properly, as shown in Figure. ![]() In Internet Explorer, go to View --> Encoding --> Auto-Select. If there's already a check mark next to Auto-Select, or if that doesn't help, go to View --> Encoding --> More, and choose the nationality that best matches the document you're viewing. The default code page for sites in English is Western European (Windows) . In Firefox and Mozilla Suite, go to View --> Character Encoding, and select Western (ISO-8859-1) for sites in English, or another nationalization that more closely matches the site you're viewing. If you find yourself returning to this menu often, go to View --> Character Encoding --> Customize to choose which code pages are displayed in the top-level menu. With either browser, some trial and error may be necessary before the site displays correctly. |

16 May 2008: Pictures Don't Show Up in Some Web Pages Recently, some icons, pictures, and photos appear to be missing from all sorts of web pages. Sure, these sites are loading faster, but some sites (you know which) aren't as much fun as they used to be. There are a bunch of things that can cause this problem. First, clear your browser cache to remove any corrupt data that your browser might be using to display pages. In Internet Explorer, go to Tools --> Internet Options, and in the "Temporary Internet files" section, click the Delete Files button. Check the "Delete all offline content" box, and click OK. If you're using Firefox, go to Tools --> Options, choose the Privacy category, and click the Clear button next to Cache. In Mozilla Suite, go to Edit --> Preferences, choose the Advanced --> Cache category, and click the Clear Cache button. Some improperly configured firewall software particularly Norton Internet Security and Norton Personal Firewall can interfere with images in some web sites. Temporarily disable your firewall; if that helps, consult the firewall's documentation (specifically relating to the anti-hotlinking features) to fix the problem. (Note that neither the Windows Firewall nor most firewall-enabled routers typically exhibit this problem.) Ad-blockers may also be suppressing content you want to see. By design, ad-blockers block images, animations, inline frames, and other content served up by certain sites, but your ad-blocker might be blocking more than just ads. Many sites also pull non-ad content from these same servers, sometimes for economic or technical reasons, but primarily in an attempt to thwart ad-blockers. Either way, turn off your ad-blocking software to see if that solves the problem. Finally, bad proxy settings can break all sorts of things in web sites. If you're surfing from work, your employer may require you to go through a proxy server; turn it off and see if the problem stops. Likewise, if you're surfing from home and you're using a proxy server, you may have to turn it off to view sites reliably. In Internet Explorer, go to Tools --> Internet Options, choose the Connections tab, and click the LAN Settings button to configure your proxy server. In Firefox, go to Tools --> Options, choose the General category, and click the Connection Settings button. In Mozilla Suite, go to Edit --> Preferences and choose the Advanced Proxies category. |

17 May 2008: Put an End to Pop-Ups There should be a law against pop-up advertisements. I hate having to close all those windows when I'm trying to get my work done. Alas, I suspect anti-pop-up laws would be about as effective as anti-spam laws. But that doesn't mean you can't take matters into your own hands and stop the madness (more or less). In the old days, all you had to do was install a third party pop-up blocker, and you were set. Today, all major browsers come with built-in pop-up blockers (though some are better than others). The problem is that pop-ups are no longer limited to web sites, which means your anti-pop-up arsenal must grow to keep up. To block web-based pop-ups in Internet Explorer, go to Tools --> Pop-up Blocker Turn On Pop-up Blocker. Of course, some sites use pop-up windows for purposes other than advertising, so you may decide to exclude sites from the blocker from time to time to allow their pop-ups to work. To do this, go to Tools --> Pop-up Blocker --> Pop-up Blocker Settings, type (or paste) the URL of the site into the "Address of Web site to allow" box, click the Add button, and click OK. Unfortunately, IE doesn't block all types of pop-ups, so a few windows may still poke through. ![]() Both Firefox and Mozilla Suite block more types of pop-ups than Internet Explorer, but only Mozilla Suite makes it easier to add exclusions. In Mozilla Suite, go to Tools --> Popup Manager --> About Popup Blocking to turn on the feature. (You're also prompted to turn on the blocker the first time a web site tries to show a pop-up window.) When you want to allow a pop-up from a particular site, go to Tools --> Popup Manager --> Allow Popups From This Site, and click the Add button to exclude the site (see Figure). Firefox is the only major browser to block pop-ups by default. To permit pop-ups from certain sites, go to Tools --> Options, choose the Web Features category, and click the Allowed Sites button next to Block Popup Windows. What if you have your browser configured to block pop-ups, but they're still occasionally showing up? If you see pop-ups when you're not surfing the Web, your PC may be infected with spyware , software designed to display advertisements and sometimes even monitor your surfing habits. Spyware, adware, and other types of malware (malicious software) come from some web sitesand also piggyback on some downloadable applications (commonly P2P file-sharing programs and, strangely, many weather forecasting desktop applications). Note: Firefox and Mozilla Suite also give you more control over JavaScript, the programming language used to facilitate most pop-ups and add some other annoying traits to web sites. To tweak the JavaScript settings in Firefox, go to Tools --> Options, choose the Web Features category, and click the Advanced button next to Enable JavaScript. In Mozilla Suite, go to Edit --> Preferences --> Advanced --> Scripts & Plugins. In either browser, you can prevent sites from moving or resizing windows, changing the text in the status bar, and more by simply turning off the respective options. Malware can be difficult to remove manually; the Add or Remove Programs control panel window is typically useless here. To get rid of these kinds of pop-ups, you'll need to install antispyware software. Among the best free antispyware tools are Spybot - Search & Destroy (http://www.safer-networking.org ) and Ad-Aware (Ad-Aware @ Lavasoft - The Original Anti-Spyware Company - Lavasoft ). Also recommended is Microsoft's own AntiSpyware tool (http://www.microsoft.com/downloads/ ), which is free and worth a look. Note: Keep in mind that no antispyware program offers complete protection, so you may want to routinely scan your system with several of the antispyware tools listed here, as well as antivirus software, to keep your PC malware-free. Whatever package(s) you use, frequently run the tool's updater to make sure it's current on the latest threats . |

18 May 2008: Stop That Browser Hijacker! I clicked a link on a web page, and I was suddenly transported to a search page I didn't recognize. The same thing happens on a bunch of different sites. Are these web sites broken, or is something else wrong? Your PC is infected with a browser hijacker , a form of malware that redirects the links in web sites to special advertising sites that generate revenue for the person who wrote the hijacking program. To get rid of the hijacker, use one or more of the up-to-date antispyware tools. If you don't have an antispyware program on your system, getting one after an infection can be difficult. Hijackers have a nasty sense of self-preservation and tend to block access to web sites offering antispyware tools. One way to get around a browser hijacker is to open the Windows Control Panel. If you don't see the task pane on the left (see Figure), go to Tools --> Folder Options, click "Show common tasks in folders," and click OK. (You can turn it off later by returning here and selecting "Use Windows classic folders.") In the See Also box that appears on the left, click the Windows Update link. The window that appears is a regular Internet Explorer window, but with a twist: this window is designed to download updates to Windows when IE has been disabled. It's typically unaffected by hijackers and other malware. From here, you can surf to any of the antispyware sites, download some utilities, and remove the hijacker. Note: If you know the exact URL of the .exe file to download, such as http://aspect1.tucows.com/files/spybotsd.14.exe , you can often get past a hijacker by typing the URL in your browser's address bar. With no links for the hijacker to redirect, the download should start right away . ![]() Note: Browsers based on the Mozilla engine, such as Firefox and Mozilla Suite, are better at saving form information, except under certain circumstances. For instance, if a form is generated on the fly, Mozilla browsers usually can't save the text you've typed into it. |

19 May 2008: Stop Annoying Animations The dancing hamster was cute at first, but now it's getting on my nerves. Everywhere I go on the Web, something is pulsating, flying across the screen, or playing music. How can I make this online circus stop? Pressing the Esc key stops most animations, but this is a temporary fix and works only with animated .gif image files. If you want to permanently disable .gif animations altogether in Internet Explorer, go to Tools --> Internet Options, click the Advanced tab, and remove the checkmark next to the "Play animations in web pages" option (see Figure). You can also turn off sounds and videos with similar settings in the same section. Click OK when you're done. ![]() In Firefox and Mozilla Suite, type about:config into the address bar to show the staggering list of all available fine-tuning options for these browsers. Find image.animation_mode in the list (type something like anim in the Filter field to locate it quickly), double-click the option, and type none in the Enter String Value box. If you don't want to completely disable animations, you can type once here instead (normal is the default) to let sites play all animations only once, but never repeat (loop) them. Click OK when you're done. Other types of animations require different strategies. If the animation, video, or sound is coming from a Java applet, the only way to stop it is to turn off Java support altogether. In Internet Explorer, -go to --Tools --> Internet Options, click the Security tab, and click the Custom Level button. In the JavaVM section, select Disable Java, and then click OK in both boxes. In Firefox, go to Tools --> Options, choose the Web Features category, remove the checkmark next to Enable Java, and click OK. In Mozilla Suite, go to Edit --> Preferences, highlight the Advanced category, remove the checkmark next to Enable Java, and click OK. JavaScript, not to be confused with Java, is often used to create flyovers (where a button or icon changes when you move the mouse over it) as well as cursor trails (the flying bits that follow your mouse pointer). To disable JavaScript in Internet Explorer, go to Tools --> Internet Options, click the Security tab, and click the Custom Level button. In the Scripting --> Active scripting section, select Disable, and then click OK in both dialog boxes. In Firefox, go to Tools --> Options, choose the Web Features category, remove the checkmark next to Enable JavaScript, and click OK. In Mozilla Suite, go to Edit --> Prefrences --> Advanced --> Scripts & Plug-ins, uncheck the Navigator box, and click OK. ![]() Of course, none of this will disable plug-ins, such as Flash. To turn off Flash animations in Internet Explorer, you must uninstall the Flash player using Macromedia's elusive uninstaller tool, available at Adobe - Flash Player Support (search the knowledge base for "uninstall"). But in Mozilla Firefox and Mozilla Suite, you can use the powerful Adblock extension, available for free at mozdev.org - adblock: index , to selectively hide animations. Once it's installed, restart your browser, and then go to Tools --> Adblock Preferences. Open the Adblock Options menu, and if the Obj-Tabs entry doesn't have a checkmark next to it, click Obj-Tabs and then click Done. Thereafter, a little tab labeled Adblock will protrude from any Flash animation on a page (see Figure above); just click the tab to show the address of the ad, and then click OK to begin blocking that particular Flash animation. Adblock supports wildcards, so, for instance, you can block all Flash animations from a particular server, rather than having to do it manually for each one. The next time you click an Adblock tab, you'll see the address of the .swf file, like this: http://advertising.server/ads/chipmunk.swf Just replace the filename with an asterisk (*), like this: http://advertising.server/ads/* to block all the files from the /ads/ folder on that server. Adblock will continue to hide these animations until you manually remove the corresponding rule from the Adblock Preferences window. Note: Of course, Adblock can block all animations with the rule, *.swf. But since some sites use Flash exclusively, don't be surprised if you occasionally encounter completely blank pages . |

20 May 2008: Solve the Blank Form Mystery I filled out a form on a web page and clicked Submit, only to be told that there was something wrong with what I'd entered. When I clicked Back to return to the previous page, everything I typed was gone! What's wrong with the site? This is caused by a bug in your web browser, and not the web site. All versions of Internet Explorer, and older releases of Netscape (Versions 4.x and earlier), are affected by this bug. To date, no browser handles form data in previously visited pages perfectly, but there are a few workarounds. For one, most web site designers are aware of the bug and have built their web sites accordingly. So, if you submit a form and then need to go back and change what you've typed, don't press your browser's Back button; rather, look for a Back button or Edit button right on the page , and click it to safely modify your text. Next, make a habit of performing an impromptu backup before you submit any form. For instance, if you've written a long message, click in the text box, press Ctrl-A to highlight all the text, press Ctrl-C to copy it, open a text editor such as Notepad, and press Ctrl-V to paste it. (Repeat these steps for any long field in the form.) If you're later forced to return to the page by pressing your browser's Back button and the form is emptied as a result, you can simply paste your text back into the form. Finally, Mozilla Suite can pre-fill most types of web forms. Just before submitting a form, select Edit --> Save Form Info. Then, if the form is blank when you return (or if you encounter a new form requiring similar data), select Edit --> Fill in Form to restore your data. Note: RoboForm, can also save form data, and it works with Internet Explorer and Firefox as well as Mozilla Suite . |

21 May 2008: Open PDFs Outside the Web Browser If I double-click a PDF file on my desktop, it opens in Adobe Acrobat. But if I click a link to a PDF file on a web page, the PDF opens in my browser window instead of Acrobat. How do I get PDFs to open in Acrobat all the time? When you view a PDF in a browser window, you're using an Acrobat plug-in that's installed automatically when you install Acrobat Reader (or the full version of Adobe Acrobat, for that matter). There's an option in Acrobat's Preferences dialog (go to Edit --> Preferences and choose the General category in Acrobat 5.x and 6.x or the Internet category in Acrobat 7.x) called "Display PDF in Browser"; unchecking this box should disable the plug-in, but unfortunately this option often doesn't always work. In this case, you'll have to take matters into your own hands. To bypass the plug-in, right-click links to PDF files and select Save Target As (Save Link As in Firefox or Save Link Target As in Mozilla Suite) to save them to your hard disk instead of opening them in the browser. (In Mozilla Suite, you can also hold Shift while clicking links to save their targets.) To disable the Acrobat plug-in altogether, exit your browser, open a Search window (Start Search --> All files and folders), and, in the "All or part of the file name" field, type nppdf32 . In the "Look in" list, choose Local Hard Drives, and then click the Search button. In a few minutes, you should see at least two (and possibly more) copies of the nppdf32.dll file. Delete all copies of nppdf32.dll , and close the Search window when you're done. (If you want to reinstate the plug-in, just reinstall Acrobat Reader.) The next time you click a link to a PDF file in any web page, your browser will prompt you to either save the file or open it with the default program (presumably Acrobat). |

22 May 2008: Control Tabbed Browsing I upgraded to Firefox some time ago, and while I like it, I can't say I've ever warmed up to the idea of " tabbed browsing." Every so often I open a link in a tab instead of a new window by accident, and I can't seem to close it fast enough. It's infuriating that I can't turn them off completely. Some people like tabs because they reduce screen clutter, but if you like to view pages side by side, for example, tabs are just a nuisance. In Firefox, Ctrl-clicking a link opens it in a new tab, but Shift-clicking opens it in a separate window. (In Mozilla Suite, however, Ctrl-click opens new windows and Shift-click saves links.) To disable all tabs in Firefox permanently, install the free Tab Killer extension (available at (http://extensionroom.mozdev.org/more-info/tabkiller ), and restart Firefox. Firefox will now ignore any attempts to open new tabs, instead opening links in the current window. To have Firefox open such links in new windows, go to Tools --> Extensions, highlight Tab Killer, click the Options button, check the "Open new windows instead of new tabs" box, and click OK. Conversely, Firefox users who despise the pileup of windows and will happily put up with tabs to keep the browser window tidy can install the free Single Window extension (https://addons.mozilla.org/extension...info.php?id=50 ) or the free This Window extension (http://extensionroom.mozdev.org/more-info/thiswindow ). While you're at it, peruse both of these sites for dozens of other extensions that expand or tame this controversial feature. For instance, if you don't want to pick sides at all, you can install the free "Open link in…" extension (https://addons.mozilla.org/extension...nfo.php?id=379 ). With this extension in place, right-clicking any link will display five different options: "Open Link in New Window," "Open Link in New Tab," "Open Link in New Background Tab," "Open Link in New Background Window," and "Open Link Here." |

23 May 2008: Faster Downloads Without the Hassle Downloading files from the Web takes forever, and sometimes the progress bar just stops! How can I kick-start downloads? You need a download manager (sometimes called a download accelerator), a program designed to eliminate many of the inefficiencies in the download process. Unfortunately, most download managers are so cumber-some and poorly designed that you'll eat up a lot of time just setting them up before you begin each download. One of the only decent download managers is Download Express, available for free from Offline browsing, stream downloading and productivity software - MetaProducts Corporation (see Figure) ![]() Note: To integrate Download Express with Firefox and Mozilla Suite, install the MetaProducts Integration plug-in, which allows you to download any item with a right-click. Better yet, use the DownloadWith extension to make Download Express your default down-loader for any or all file types . After installing Download Express, go to Start --> All Programs --> MetaProducts Download Express --> Download Express Options, and click the Integration tab. Check the "Use alternative integration method" box and click OK. (You'll need to exit and relaunch Internet Explorer for the change to take effect.) |

24 May 2008: Set Download Defaults in Mozilla Suite When I download files with Mozilla Suite, I'm often asked if I want to open the file or save it to my hard disk. Even when I check the "Always perform this action" box, Mozilla Suite keeps asking me. How can I stop this endless badgering? This bug has been around for a long time in Mozilla browsers, although it was mostly fixed in Firefox. The solution is to install the free DownloadWith extension, available at mozdev.org - downloadwith: index , along with the Download Express download manager discussed above. Install both programs, restart Mozilla Suite, go to Edit --> Preferences, and choose the DownloadWith category. Click the "Create new application" button, select MetaProducts Download Express from the list, and click OK. Then, choose the "Automatic download" tab, select the "All files" option, and choose MetaProducts Download Express from the Application drop-down list. Note: If you only want to automatically download certain file types, select "Specific files" instead of "All files." Then type a filename extension in the "File type" field, minus the dot (for example, enter zip for .zip files). Choose MetaProducts Download Express, from the Application drop-down list, and then click the Add/Update button to add your new entry to the list . Click OK when you're done. From now on, to download a file from a web site, just click the link. Choose a folder to save the file in, and Download Express will handle the rest automatically. |

25 May 2008: Surf Anonymously for Free I visited some web site that showed my IP address and even the state where I live. This is freaking me out. How can I mask my identity when I'm on the Internet? Use a proxy server to mask your IP address (and yes, your state) from the web sites you visit. As the name implies, a proxy server stands between your browser and the sites you surf, in effect "hiding" you from prying sites. Once you set up a proxy server, all information you send and receive with your browser goes through that server (email and other programs must be configured separately to use the proxy). Most large companies use their own proxy servers to help protect the data on company PCs from prying eyes, but you don't have to work at a big company to get the same protection. Go to Proxy 4 Free - Public Proxy Servers, Anonymous Proxy, Proxy List - Protect Your Online Privacy! , click "Section 1.1 " in the list on the left, and find any server marked "anonymous." Highlight its IP address and press Ctrl-C to copy it to the clipboard; also note the port number shown in the adjacent column. Next, configure your browser to use that proxy server. If you're using Internet Explorer, go to Tools --> Internet Options, choose the Connections tab, and click the LAN Settings button. Check the "Use a proxy server for your LAN" box, and then press Ctrl-V to paste the IP address into the Address field. Type the appropriate port number (usually 80 or 8080 ) into the Port field, and click OK when you're done. The procedure is pretty much the same for other browsers. If you're using Firefox, go to Tools --> Options, choose the General category, click the Connection Settings tab, and select "Manual proxy configuration" (see Figure). If you're using Mozilla Suite, go to Edit --> Preferences --> Advanced --> Proxies, and select "Manual proxy configuration." (If you can't load the page, the proxy server is down; just choose another proxy server from Proxy 4 Free and try again.) From here on, until you disable the proxy, every site you visit will see your proxy server's IP address instead of yours. ![]() What Can They Find Out About You? Your IP address is sent to every web site you visit. While no one can determine your exact street address directly from your IP address, there are ways to infer this information with elaborate tracking schemes. Think of your IP address as a serial number, a unique identifier some web sites can use to identify you when you visit. For instance, let's say you make a purchase from an online store that sells toasters. As soon as you pay for that new four-slicer, the store records your name, street address, credit card information, and IP address. Provided the toaster store keeps your private information private (and presuming its database isn't hacked into), you've got nothing to worry about. But can you say the same thing for that other site where you just signed up for a contest giving away free iPods? This is where advertising comes in. Most ads on many web sites originate from only a handful of companies, and those companies track who's looking at their ads, even when you don't click them. If you view a page at a news web site that displays a banner ad hosted by, say, Adknowledge.com or Targetnet.com, and then you sign up to win a free iPod on another site that has another ad from the same agency, that ad server knows you've visited both sites. What's more, if the ad agency is in cahoots with the people who are giving away the iPods, they now have your email address, street address, shoe size, and anything else you typed into the sweepstakes signup page. Now, most folks have dynamic IP addresses, which change every time they start a connection but these connections can remain active all day (or, with a router, for weeks at a time), which means your IP address can be used to track quite a bit of your online activity. What's more, many unscrupulous sites use so-called tracking cookies to do the same thing, tagging your PC with a unique serial number that can be read as you visit different sites. So, how can you stop the snooping? Most antispyware software is designed to scan your system and delete any tracking cookies it finds, but you may want to take it one step further and configure your browser not to accept any cookies from these sites. You can get a list of known tracking sites from Spyware Encyclopedia - Browse cat=Tracking%20Cookie . (If this feels like overkill, block only those sites responsible for the cookies your antispyware software finds on your PC.) To block cookies in Internet Explorer, go to --> Tools --> Internet Options, choose the Privacy tab, and click the Sites button. In Firefox, go to --> Tools --> Options, choose the Privacy category, expand the Cookies section, and then click the Exceptions button. In Mozilla Suite, go to Tools --> Cookie Manager --> Manage Stored Cookies. Next, install ad-blocking software such as the Adblock extension and use a proxy server to mask your IP address. Finally, get yourself a router, if you don't have one already, to protect your PC from other types of intrusions. Every byte of data you send and receive with your web browser will be sent through the proxy server. Unless you know and trust whoever is hosting that server, you should always disable the proxy before sending sensitive information (e.g., your home address, credit card details, etc.). If setting up a proxy server sounds like overkill but you'd like to have protection on the odd occasions when you visit a site that you suspect may be harvesting information about you, an alternative is to use a free, single-serving proxy server, such as Proxify (ProxifyŽ anonymous proxy - surf the Web privately and securely ), The Cloak (start surfing ), or Anonymizer (Anonymous proxy servers, by Anonymizer, hide IP addresses for surfing anonymously. ). Just type or paste the URL of the site you want to visit into the text box on any of these pages (at the Anonymizer site it's the Private Surfing box in the upper right corner), and press Enter. The proxy site will load up the page, allowing you to surf anonymously for this session. Click links in the page to continue surfing anonymously, or use your browser's address bar, bookmarks, or Internet Shortcuts to return to normal, non-proxy surfing. |

26 May 2008: Pick the Default Email Program I use Eudora to read my email, but Outlook appears at the top of my Start menu. Can I put Eudora here instead, or does Microsoft want me to switch to Outlook? Well, yes, Microsoft does want you to switch to Outlook. And they want you to use Word and Internet Explorer, rather than WordPerfect and Firefox. If they had their way, you'd be brushing your teeth with Microsoft Toothpaste. The good news is that you can have it your way ; Sinatra would be proud. To change the program that appears in your Start menu, right-click the Start button, select Properties, and choose the Start Menu tab. Make sure the "Start menu" option is selected, click the Customize button, and choose the General tab. Pick the desired program from the drop-down Email list in the "Show on Start Menu" section, and click OK. (You can also remove the entry entirely by clearing the checkbox next to "E-mail."). But the Start menu entry is only a small piece of the puzzle. What's particularly important is the default email program the program that opens automatically when you click a mailto : link in a web page or email a file from within another application. To make your favorite email program the default, open the Internet Options control panel, click the Programs tab, and choose your program from the drop-down Email list. If you don't see your favorite email program here, see the "Add or Remove Email Clients& |
