Nit-picking with some other comments that describe uBlock Origin as an "ad blocker". Yep, it's an ad blocker, but that's too narrow and limited a description. Its value to me goes way beyond blocking ads. More broadly, it allows me to block content I don't want to see. And it does that superbly.

Using it since the beginning, never disappointed.

Funciona realmente bien, excepto por el echo que , por alguna razón que desconozco, borra los comentarios que se hacen en cierta página web (anime flv)

Update: uninstall and reinstall worked and everything if fine again:)

Does not work anymore. 2018/5/5 no more lists in the options:(

It works perfectly

Great, functional and convenient add-on. BUT lately can you please check out the following ad-block detector and counter-measure script which USED to be ignored by uBlock but now completely stops it... sorry for posting this here, I could not find a contact email...

Doesn't block Google analytics
