When I first added this Extension it worked well but recently far too many add are appearing on Facebook.

It do not block Publicity posts, only the ones on the right

This addon was good some months ago, now it just doesn't block adds, even I tried reinstalling, enable/disable option, but nothing changed, I hope it could be updated soon.
Anyway, thanks for the help, it was great when it was useful.

It works but it constantly freezes up the page, so had to uninstall. If you fixed that, it would be great.
