Hasta ahora me a servido para bloquear anuncios que me cubren mucho la pantalla.

blocks all YouTube ads. loved it

Very good!

complete trash!!!! after a time, this adblock never works

Since adding this to Firefox I have yet to see an ad. To the devs: keep doing what you're doing. Thank you for your work.

Blocked exactly zero ads. Installed "Ad Block Plus" and it blocked all ads on same pages.

best blocker!!!!
