Favourite Firefox Plugins

What are the Firefox plugins you just can no longer live without?

Mine are mainly security but i do use a few cool ones
Noscript
adblock plus
better privacy
element hiding helper for adblock plus

stylish - this is a really cool add on which rethemes sites for you. so you can go on google (or any site) and it looks completely different - you can download 1000's of themes people have made and choose the ones you like

I also use exif for extracting the exif data from photos as it tells me a lot about the eperture settings etc

greasemonkey for running customisation scripts

 

adblock was great...especially here for annoying signatures

 

cannafox..

 

autopoke for facebook...
yea I'm lame.

 

I don't really use all that many plugins but the one's I do have are.

1)Taboo
2)Colorful tabs
3)Greese monkey
4)DownThemAll

 

I pretty much just use adblock but I cant live without it anymore lol
