Can't live without this addon! Rated 5 out of 5 stars

So happy to see that this is now working with Australis (UI overhaul) on Nightly Firefox. Here's a small bug I've noticed when going to customize the toolbar: the tree style tabs become temporarily tabs-on-top

Thanks for all your work on this, I use so many tabs throughout a given day - especially in bug triage - that this addon makes gtd possible.

This review is for a previous version of the add-on (0.14.2013100901.1-signed).
