Your Favorite Firefox Add-on/Plugin

[Crashfan3]

I just upgraded to Firefox 4 today but the thinner bar on top cut off my Rainbow Dash persona (don't hate), so I figured I'd get a random toolbar to expand the top part. I found this toolbar called fire.fm and I really like it. It is basically a last.fm player built into Firefox that gives me no excuse not to have music playing while browsing the internet, which should in turn expand my music library.

So what are your favorite firefox addons/plugins?

inb4 everyone says adblock plus / noscript.
