I recently searched through the mozilla thunderbird extensions website and found 4 extensions that I didn't know about that actually prove to be quite useful. I use Thunderbird 2.0.0.12 on Foresight Linux and have tested all of these extensions and verified that they work on that environment.

Search for Sender

If you're like me, you like to group like items together in your inbox. With this extension, you can group emails from the same sender as quickly as a right click. Really, it's just a shortcut that places the sender email up into the search box and searches for you. The nice part is, with this extension, you don't have to type it. Quick, easy, and simple. This has quickly become an extension that I cannot live without.
