@jelv, you don't know what you're talking about. Tabmixplus doesn't handle collections of tabs at all. I use it together with Tabmixplus. Let's hope it gets upgraded to support Fx 3.6 soon. Fx 3.7 doesn't make much sense as it's not even in alpha and is still bound to change a lot.This review is for a previous version of the add-on (0.5.2009110501).
