Rated 5 out of 5 stars

Absolutely necessary ! Great extension ! Thanks to the creator of this add-on :-) But isn't it just silly that Firefox 4.0 developers removed natively "browser.tabs.tabMinWidth and browser.tabs.tabMaxWidth" from about:config ?! It was just so easy to change the settings... it took 30'' !!! Now of course it's easy too with this ext... but having to install another add-on just for that is frankly stupid, IMHO...Anyway fortunately the creator of this add did what should have done Moz Fx4 developers, so thanks again !
