I LOVE LOVE LOVE this extension! Rated 5 out of 5 stars

Every page these days had tons of annoying and ugly ad banners all over it. I love the fact that I can surf the net in peace, not having to be bombarded by all of those annoying ads. Webpages look MUCH better without them.
Also, some ads distort the look of the page, pushing content either down or to the side, making you have to scroll back and forth to read it sometimes. This add-on gets rid of that. Once you've blocked an ad, the space it took up is made smaller.

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