One of the things I like about Firefox is that there are many people out there writing some pretty cool extensions. Below is the list of the extensions I am using and I am always looking for new ones that can improve the user experience or make my time surfing the Net easier.

DOM Inspector
Domain Lookup
DownThemAll
EC2 UI
FireShot
Live HTTP Headers
Meebo
RefControl
ScribeFire
SEO For Firefox
ShowIP
YSlow

You can find more information about the above extensions by going here.  Domain Lookup hasn’t been added to Mozilla yet so you can find it by going here.

What is your favorite extension?
