When ext. first came out it worked perfectly with no issues, then shortly after they became quite popular, and slowly started accepting bribes to take companies off the blacklists. Started slow and progressively got worse.
Ditched this for uBlock Origin (works fantastic) very light on ram usage too.

Adblock works fine for most feature. I don't get ads on Facebook, but I've lately been getting postings from sites of absolutely no interest to me. I "don't show" them, but others keep coming.

I can't figure out how to download and install ABP on Firefox. I paid for a year, but keep getting prompted to upgrade AB to ABP.

Stopped working on YouTube as of today. Otherwise it's great.

Bin zufrieden, wundere mich nur, dass ich nach einiger Zeit Adblock neu aktivieren muss!
