Makes life so much easier! Love this extension!

Tree Style Tab de Piro (piro_or)

This is (or was) one of my favorite extensions, but then they decide to remove one of the most fundamental and needed features: grouping. It's a basic feature that should be in this main extension, and not in a separated one!!! The developer must have their decision reasons and probably related to maintenance burden... Still I'm kind of disappointed and pretty much lost at least 2 of 5 stars with this removal.

I have been very happy using Tree Style Tab and I heartily recommend it.

However, with the latest version the "Create Group from Tabs" command was removed from the context menu and moved into another companion addon, rather than using the already built in function that lets you customize the context menu.

Further, this new addon is not monitored by Mozilla - which obviously makes the addon a no go for those of us who are concerned with security.

Luckily the old version is still available - here's hoping there's no security risk in using that one!
