There are tons of wonderful Firefox add-ons. In fact, that is what makes this browser stand out among other browsers. However, be cautious to install every other extension you think may be cool. Firefox performance can significantly degrade when you install many/random extensions.

Anyway, for what it’s worth, following is the list of Firefox extensions that I can not live without (alphabetically):

• Aardvark
• Add N Edit Cookies
• CookieSwap
• del.icio.us
• Extended Statusbar
• Fire Encrypter
• Fire Bug ( I bless the day Joe Hewitt started programming!)
• MeasureIt
• Server Spy
• Talkback (well, i can live without it but keep it installed as courtesy to Firefox)
• User Agent Switcher

P.S. I am not trying to be lazy or annoying when not linking these plugins. First, such links may soon get invalidated because URLs change all the time, second - if you google “firefox plugin <addon name>” you will find any of them, easily - promise!
