The following is a list of hidden
Mozilla prefs I know of that can be quite helpful. Many
of them are taken from
http://www.mozilla.org/unix/customizing.html (NOTE: Not all the
prefs listed on that website are over here). Others will be added as and
when I find out about them.
Browser // Patch for bug 143687
has been checked in on 21-Oct-2003.
// Now you can view favicons in the toolbar with the following pref set.
// 0 - Do not display favicons (default)
// 1 - Display only if present in cache
// 2 - Always load them
user_pref("browser.chrome.load_toolbar_icons", 1);
// Enable truetype fonts. Use these prefs only if you have a non-xft
// build (e.g. default Linux nightly builds from mozilla.org).
//
// First of all, add a few directories that contain truetype fonts, e.g.
user_pref("font.directory.truetype.1", "path-to-directory");
user_pref("font.directory.truetype.2", "path-to-directory");
// Now enable freetype
user_pref("font.FreeType2.enable", true);
user_pref("font.FreeType2.unhinted", false);
// Finally, also check out how to get Mozilla widgets like menu, toolbar,
// dialog boxes, etc to use freetype fonts on my userChrome.css page.
// EXPERIMENTAL // Nightlies after 12th July 2002 have a fix to bug 28586. What it means
// is that Mozilla will display an error page instead of the annoying
// dialog box. Add the following pref to see it in action.
// NOTE: This feature is experimental and can crash your
browser
// See bug
157102.
user_pref("browser.xul.error_pages.enabled", true)
// Turn off domain guessing (which adds www. and .com) for link URLs
// This means that if you type http://cnn/, Mozilla will not try
// to go to http://www.cnn.com. For more details read
bug 34943 // This will also fix the nasty bug where clicking in history folder
// results in Mozilla going to www.apps5.oingo.com
user_pref("browser.fixup.alternate.enabled", false);
// NOTE:
// Recent Nightlies - Use Edit->Preferences->Navigator->Downloads.
// Mozilla 1.0 - Use the pref.
//
// Modify the behaviour of the new download manager
// 0 - New download manager
// 1 - Old download manager (separate dialog boxes for each download)
// 2 - No download manager window popup (you can always click on
// Tools->DownloadManager to check on the progress)
user_pref("browser.downloadmanager.behavior", 2);
// Get rid of the Print Progress dialog that pops up when printing.
user_pref("print.show_print_progress", false);
// This pref displays the alt-text instead of the "image-not-found" image
// true = force ALT text for missing images to be layed out inline
user_pref("browser.display.force_inline_alttext", false);
// To set the user-agent string to whatever you desire. Following are a few examples.

user_pref("general.useragent.override", "Mozilla/5.0 (compatible; MSIE5.5; Windows 98;");

// More important, disable JS windows popping up a new window on load
// (as lots of porn and spam sites do): user_pref("dom.disable_open_during_load", true);
// See bug 93827 for details. The functionality of "print.print_method" prefs is the
// following on Unix

user_pref("mailnews.nav_crosses_folders", 0);
// In order to prevent stress on news servers, Mozilla collapses
// news servers by default at startup so that it doesn't check for
// new messages. You can enable the persistance of newsgroups by
// adding the following pref. Related thread on n.p.m.mail-news user_pref("news.persist_server_open_state_in_folderpane", true);
// To make your account use movemail instead of POP3,
