Mozilla Connect

It is very unfortunate that there has not been any development in this regard even though it has been almost a year since then. User comments should be taken into account.

I am planing to swicth to chrome until firefox have tab groups. I hope it won't take so long. Tab grouping is a must for me.

When will it be avaiable?

This feature is a must. Chrome tab grouping is a very good example.    

Still waiting for the tab groups...
