Rated 3 out of 5 stars
This addon's ratings seems to be based on websites reputation than if it has any real threat. And the website may change, but the reputation is the same. Sure you can vote it the site gets better, but the earlier votes count just as much. So it it was a really bad site that became good, it would be almost impossible for its rating to change because of the system. If the earliest votes counted less or were removed, it would probably be a more fair system.
Its not bad though, keeps you from a lot of bad sites, but a lot of good sites too.
