Rated 4 out of 5 stars
I like this addon because it works instantly activated by hotkey, no lags and it's customizable. I've been using it for a while and I still haven't updated my FF to 3.5 for incompatibility. But it takes too long and it's the only incompatible addon in my addons set. Unfortunately I won't wait anymore, I'll have to let it go :(This review is for a previous version of the add-on (0.2.1).
