"Installation aborted because the add-on appears to be corrupt." do i need to say more?

Why does it beep every time it blocks an advert? Just shut up.

When i make a research on google, i first have a page with good result, and within a short time (1-2 seconde), my page is reload, with new website in first recommandation that are clearly commercial ads. So it's claim to remove the ads, but it's had it in fact.
I desactive just this extension, and i didn't have the problem anymore.
