The End of Tree Style Tab... and Firefox, for me. Rated 5 out of 5 stars
Good by my dear Firefox with Tree Style Tab. Seems Chrome will lead on this from now - take look on "Tabs Outliner" in chrome store. I think there is a lot of ideas can be borrowed from it for this addon. Yet first i think worth return to Firefox ability successfully maintain a hundred of tabs, at least... i remember in 3.6 i manage to open 1000....This review is for a previous version of the add-on (0.14.2012050301).
