Rated 4 out of 5 stars

Great add-on. Probably the most comfortable way of using bugmenot.com's outstanding service.
However, the add-on doesn't give any feedback if a site site is, for some reason, blocked on bugmenot.com. In that case it just does nothing which is a bit irritating.
That being said, it's still a great add-on but I can only rate it 4/5.

This review is for a previous version of the add-on (2.2).
