Rated 5 out of 5 stars

I agree with the other uses, it would be GREAT if it could compact ALL the databases.
Also, I would really like it if you added a cleaning timer (eg: Clean every 48 hours), since I use Firefox Preloader to keep FF in my RAM so FF it only restarts when my computer does (which doesn't happen often).

This review is for a previous version of the add-on (1.1).
