Just may be the coolest Firefox extension yet.

Viamatic foXpose extension has got to be the coolest extension yet. This extension will build a single page of thumbnails for all open tabs in the current session of Firefox. This lets you quickly look through your open tabs and navigate to the one you need. Sure, reading the short title that appears on the tab may be a possiblity if web devs didn't push so many keywords into the titles and make them useless - plus the more tabs open the less of the title you are going to see.

This extension is a must if nothing more than to check it out.
