Firefox Add-ons You Use?

Firefox is no doubt the most 'extended' browser when it comes with add-ons. What are some of the Firefox add-ons you guys use?

I use:

AdBlock Plus - For blocking ads and unwanted images.
Alexa Toobar - To roughly determine a website's traffic and popularity.
Firebug - To troubleshoot HTML/CSS/Javascript when construction web pages.
StumbleUpon - For entertainment when I am free.
