For all you Firefox users, what are some of your favorite browser extensions?

Here are mine:

Linky: Lets you open selected or all links in new tabs with a single click

Tiny-URL Creator: Lets you turn a long link into a short one for posting purposes with a single right-click

Undo Close Tab: Lets you un-close the tab you just accidentally closed

Dictionary Search: Lets you highlight a word and open a dictionary definition for it in a separate tab

IEView: Let's you open a tab in Explorer or assign a site to open in Explorer. I use this for shutterfly.com and other sites that aren't Firefox friendly.

StumbleUpon: This is a great site for wasting time. You can put in your hobbies/interests and it will recommend sites for you. Way cool.

Bumble Search: Greatly enhances web searching in many ways.

Forecastfox: Tells me the weather on the tool bar.

Colorful tabs: Just makes my tabs look pretty.

Cardgames: A bunch of solitare card games.

Soooo share some of yours
