Rated 5 out of 5 stars

I'm Missing it too, but luckily Jomel started the make one for the firefox 3.6 and higher. You can see that on tabkit.uservoice.com but I think that there's a problem with the program because it's taking a very long time. But maybe it's because 3.6 removed some options of the add-ons and Jomel has to rewrite the code (I hope not).
But Jomel let us know something so we know you're still alive (And else R.I.P.) ;-)

This review is for a previous version of the add-on (0.5.8).
