Browser search lemmingness

[tangerinpenguin]

If you are using Firefox, or another browser that lets you customize the built in search engines, what search engines do you have set up?
Mine (at home; at work, many of them are Amazon Intranet-specific):

• Google
• Amazon
• IMDb
• Java Sun [this one now appears to be broken]
• Perldoc [this one too]
• RhymeZone.com
• Wikipedia [EN]
• Allekhazam
• Wowhead
• Y!PP forums
• Lyricwiki.org [if you still do lyric searches on sites with popup ads, this may be your new best friend]
• WoWWiki
• WoW Armory
