Rated 5 out of 5 stars

I am using Firefox 3.6.8 with the latest version of Adblock (1.2.1), and my add-on is working great on Youtube. You may have issues with your add-on install. Uninstall it, clear your browser cache, and then then install Adblock again. A fantastic add-on, a must for one and all !!

This review is for a previous version of the add-on (1.2.1).  This user has other reviews of this add-on.
