Which adds-on do you like best in the FireFox browser or you browser
?

For FireFox I use Ad Block Plus, DownThemAll, FoxyProxy, ColorfulTabs, Download StatusBar, and GreaseMonkey(with a XKCD and Wikipedia script)

and now I wait for Chrome to have those :3

I don't use any at the moment, my computer is already slow enough as it is.

Mouse Gestures and Adblock Plus. Everything else is just fluff I don't need.

I have no add-on for my firefox.

Adblock Plus (with EasyElement and EasyList filter subscriptions), ColorfulTabs, and Web of Trust (WOT). Adblock Plus and WOT certainly make web browsing a much more enjoyable and safer experience with Firefox. Both are must haves in my book.

ColorfulTabs is strictly for the eye candy.

Adblock Plus - https://addons.mozilla.org/en-US/firefox/addon/1865
EasyElement & EasyList - http://adblockplus.org/en/subscriptions
WOT - https://addons.mozilla.org/en-US/firefox/addon/3456

I have pretty much al those, plus maybe All In One Sidebar and Firebug...
If only chrome and FF could merge into one!

Greacemonkey is one of my favorite add ons to use
