Mozilla Connect

I 100% support the need for UI switch option for this feature.I hated this feature and accidentally got to know from this thread how to turn it off.

I hope vertical tabs is just an option to complement horizontal tabs with grouping feature.I'd love tab names to be readable, which is a piece of crap with vertical tabs IMO.

Officially updating the status to 'In development' as our team is working hard to bring this feature to Firefox. 

Just found myself looking into what Chrome has for tabs grouping and was astonished there is no such a feature in FF  Pretty please improve FF UI.     

Great idea. It is what indeed is missing from when title bar is hidden.
