Some interesting things here, including how to kid web servers on that your mozilla browser is IE or something, useful when certain sites like on-line banking tell you to get lost because you "aren't using a Windows or Apple Mac Operating System..." Hmmm....
Tricks and hidden features in Mozilla
Last updated on Sat, 05 May 2001
This covers tricks and some hidden preferences in Mozilla. Although this sounds similar to that can be used with Mozilla. A Tips and suggestions for using Mozilla, which is about usage tips and advice, this page focuses more on little preferences and features.
The following customizations only take effect after restarting Mozilla, and a simple text editor is required to create and edit the proper files:
Much of Mozilla's colors and appearance is colored with Cascading Style Sheet files, so Mozilla's appearance can be customized with two CSS files: userContent.css and userChrome.css
These files must be placed in the chrome folder of your Mozilla profile, not the chrome folder where Mozilla was installed.
userContent.css overrides certain appearance settings of within the content window of the browser and Mail/News, while userChrome.css controls the UI chrome of Mozilla. For example, the following for userContent.css will put a thin black border around all dropdown forms, like in Netscape 4.x:
border: 1px solid black !important;
border-top-style: solid !important;
To customize the font for dialog windows, place the following in userChrome.css and modify to your heart's delight:
font-size: 3.5mm !important;
font-family: helvetica !important;
Visit mozilla.org for more examples of these CSS customizations.
Mozilla keeps many of its preferences in the file prefs.js in your Mozilla profile. You can create your own file, user.js, at the same location as the prefs.js file, to store your custom preferences. Mozilla will read the user.js file and overrule some settings in prefs.js with them.
One useful preference setting that can be added to user.js is for controling of animated images:
where value is either normal, once, or none. The default setting is normal, but once prevents animated images from looping after its first run, while none prevents it from animating at all.
If you visit a site that is blocking your browser from entering, the following preference will help with that:
user_pref("general.useragent.override", "fake agent string");
user_pref("general.useragent.override", "Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC)");
user_pref("general.useragent.override", "Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)");
