Rated 3 out of 5 stars

In Firefox 3 this was a useful add-on with a nice range of display options (tab, sidebar, window) but in Firefox 4 it clashes with the new built-in feature Panorama. It hijacks the down arrow on the tab bar, preventing the display of the Tab Groups menu, and its functionality now seems redundant. Perhaps it could be modified so as to work in conjunction with Panorama and to offer complementary functionality.

This review is for a previous version of the add-on (0.9.5.6).  This user has a previous review of this add-on.
