Sweet FF extension

[Guiness]

I'm with ya numb. Adblock, Flashblock User Agent Switcher (for those stoopid sites that arbitrarily decide though shall use IE) and Whiz RSS. Add a few search engines (Wiki, Webster, Medline) to the search bar, Redshift and pinball themes...

The ability to access multiple search engines from one pull down box is second only to the tabbed browsing, IMO.
