Rated 4 out of 5 stars

I like this add-on because I find flash very annoying often, especially when you try to read an article somewhere and it causes animated ads on the side of the text, but unfortunately it doesn't always work I'm sorry to say.
But obviously ad people do their damnedest to bypass such blocks so I can't blame the author for not being perfect really.

This review is for a previous version of the add-on (1.5.6).
