Very nice. I don't really need the "tree style" function, but displaying tabs in a vertical fashion is quite useful for me. Firefox has become much snappier than when I was using multi-row to display tabs. After disabling the tree function in about:config settings, it is now much more convenient.This review is for a previous version of the add-on (0.11.2011021901.1-signed).
