Can't stop Adblock plus telling me the installation was successful every time I open Firefox

I'M GETTING YOUTUBE ADS. many. fix and release update pls :)

efficace !!

AdBlockPlus is not really working on Youtube, Yahoo mail, and Facebook, especially Yahoo Mail, their ads are pumping audio thru my speakers, as if being displayed on my screen isn't a violation enough, the only websites i really even use on the internet, Youtube keeps telling me that I'm not allowed to block ads trying to pump their crap into my devices and home, a total violation of my boundaries, otherwise, they're mostly blocked, and Facebook blocking rarely ever worked at all, comes and goes.

Best add blocker, after installing my web browsing becomes fast and smooth.
