Tricks for Mozilla Firefox.

Fix Annoyances

Disable those damn animated GIF graphics:

Type "about:config" as a URL.
Type "animation" in Filter.
Select row, right click, select Modify.
Change value to "none" (auto saves).

Disable that damn URL drop-down

cd ~/.mozilla/firefox/*default/chrome
cp userChrome-example.css userChrome.css

Append to end of userChrome.css:

/* Hide auto-complete in address bar */
#PopupAutoComplete, .autocomplete-tree { visibility: hidden !important;
display: none !important; }
/* Remove arrow from Address bar */
.autocomplete-history-dropmarker { display: none !important; }

Disable that damn audible bell when searching:

The first method is the best way and should work. Try the others only if the first failed.

1. Type "about:config" in URL bar.
   Type "sound" in Filter.
   accessibility.typeaheadfind.enablesound = false
   accessibility.typeaheadfind.soundURL = none
   Restart Firefox.
2. /etc/profile:
   setterm -blength 0
3. xset b off (applies if X is running)

Disable that damn Macromedia Flash:

Get the extension "FlashBlock".
Or rm ~/.mozilla/plugins/*flash*
If that doesn't work, rm /usr/[..mozilla..]/plugins/*flash*

For Firefox 2, to only load images from same (originating) server:

about:config
permissions.default.image = 3

The about:config Trick

Type "about:config" as a URL.
A magic internal webpage will show the browser's settings.
The settings can be edited by right-clicking on them.
These are the same settings that are defined by prefs.js.

Those darn annoying animated GIF images can be disabled by changing this setting:
image.animation_mode, none

Suppress Default Plugin dialog

To suppress the annoying Default Plugin dialog for downloading Shockwave/Flash plugin crap, remove libnullplugin.so (one of each for Netscape and Mozilla):

/usr/lib/netscape/plugins/libnullplugin.so
/usr/lib/mozilla/plugins/libnullplugin.so
/opt/firefox/plugins/libnullplugin.so
