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...
See... https://blockadblock.com/blockadblock_basic_script.php

Doesn't block Google analytics

Low CPU/RAM footprint. Fast! :) Happy with this.

右クリックで間接的な広告や不快な要素もブロックできる点が素晴らしい。
