Rated 5 out of 5 stars
Awesome! It stops video advertisements.
I tested this at "That Guy With The Glasses" & "The Escapist." The commercials that load before the videos played about 2 seconds before they got cut-off & switched to the real video. Every video on TGWTG played the same 1 advert over & over again before I got this add-on.
It also cuts off a lot of flash adverts, but not the ones that advertise for MMORPGS (social online games).
