It is a lifesaver for letting me block the horrible things people post (since the site is run by nitwits who put a cap on how many people you can block normally).

Unfortunately, today it seemed to delete all the blocked users and keywords I had for seemingly no reason, so I have to start over. Guess I should start backing up my list with the export feature.

This addon sucks. It does not do what it claims to do. When hiding a piece of art on the website by clicking the X in the top left of a thumbnail, it does not hide only that picture, but EVERY thumbnail on the website. Also, the filters do not work at all, many times I have found photos that have tags that I have clearly set a filter for, and on top of that, there are still photos from entire categories that I have blocked! This is a garbage addon. Fix it and make it do what it is supposed to, which is ACTUALLY block things. Note: These problems are ones that I have found using Mozilla Firefox.
