Clashes with Firefox Panorama 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 unfortunately it clashes with Firefox 4's new feature Panorama. If Showcase is installed then the down arrow on the tab bar opens Showcase instead of the menu for Panorama's Tab Groups. Also, with Panorama built into the browser, Showcase seems pretty well redundant, so with some regret I've uninstalled it. Perhaps Showcase could be modified so as not to hijack the Panorama controls, and to provide some complementary functionality.This review is for a previous version of the add-on (0.9.5.6).
