Better than TabMix Plus! Rated 5 out of 5 stars

This is a lot faster, and certainly a lot more powerful to use than tabmix plus. Especially when having tabs in a sidebar where you can scroll quickly through all tabs. And grouping is wonderful, i have over 100 tabs each day and it makes it so much easier to manage!

This review is for a previous version of the add-on (0.5.6).
