After years of successful use, for last few weeks this extension is broken, even after several reinstalls. Sad to look for an alternative...

No longer working on Facebook with Firefox browser!

Todo lo malo lo borra, proteje como mi padre. Indomable extension, que maravilla.

Best one I've used, def worth a donation

just works!!

I would like to rate it 4.8, the only thing I don't like is it causes YouTube to completely freeze my computer.
So now I just turn it off (with Manage Extensions) when watching YouTube which is okay because I have an ad free YouTube account.

Very good. The best I've ever used.

Tooo good at blocking ads and malware
