Seems to be crashing Fx3 beta 3 Rated 2 out of 5 stars

Yeah, um. It seems really useful, but for whatever reason, it keeps crashing Firefox periodically and slowing it down whenever it /doesn't/ crash. At least, I'm fairly sure it's this extension: it worked fine before I installed this and when I disabled it, the problem stopped.

It does, however, make it a lot easier to manage tabs. :[

This review is for a previous version of the add-on (0.5.2008022702).
