No More Flash -- Hurray Rated 5 out of 5 stars

Flash = memory and bandwidth waste
Adblock Plus = Superb Extension

I also like to use this to get rid of really annoying auto-play videos and video-ads like Youtube, because those stupid videos on youtube and such really get on my nerves, and I am not talking about the ads.

This review is for a previous version of the add-on (0.7.2.4).
