for some weeks now my Adblock-Plus doesn't block the advertisement anymore. First it were only some ads which appeared again, now even Youtube can show me its annoying advertisement-spots.
One example (red frames)
I updated my FIrefox (57.0.1) and re-installed Adblock-Plus and added it to Firefox.
I haven't changed anything in the setup of Adblock. Adblock may show me the ads of its white list but not all the others.
Can anyone help ...?
