Bad Upgrade! Rated 1 out of 5 stars
I wish that worked--I did that and it's fine until you close your browser and when you open it again, it's gone and you have to re-install it OVER AND OVER. VERY annoying! I depend on these tabs for sites I visit several times a day and now because it harassed me until I finally installed 7.0, look like I either have to find something else or finally use Google Chrome. Very disappointing, Firefox. :- (This review is for a previous version of the add-on (18.104.22.16810620112826).
