Great, but not for Nightly. Rated 4 out of 5 stars
A great tool for those who, like me, have a problem with tab management. I use Nightly, however, and it's been causing the tabs to glitch since about a month ago (they overlap). A must-install for those using vanilla Firefox!This review is for a previous version of the add-on (0.5.0.1).
With Nightly always use the latest development build
