Rated 5 out of 5 stars

Yes. It is very nice. It does not have the CPU usage problem that someone else mentioned. I thought it did, but on restarting FF again, the problem was not there

I'd like to be able to do multiple tab selection, as in Vertigo, but the Shift + drag for groups is nearly as good.

I like the "Group tabs from here to current" command. Once I had sorted my tabs a bit manually, I used this command to make my groups, and my 140-odd current tabs are now nicely grouped and easy to navigate. Thank you.
