Now that I'm passed the original frustration of loosing all of my plugins when FF updated itself, I can voice an opinion that's more grounded. :)

I will not start complaining about all of the stuff missing compared to the TAB Mix Plus/Session Manager/Tab Groups plugins, I would miss the point I want to make.

That point I want to make is pretty simple: the first iterations of this plugin were lacking in terms of functionality and were barely usable to me. Since then, sienori, the Dev, is keeping a good pace at delivering new versions up to a point that I start to enjoy using FF again as my daily browser.

Keep it up, sienori! I suspect that like me, you are helping FF keep some of it's most loyal users when everything seemed to be doomed a few weeks back. KUDOS!
