Quite simply the best ad-blocker out there, bar none. Always the first add-on I install. It's fast and it just works.

after this all web pages stopped to load, nice way to block adds by blocking all contents

Um dos melhores bloqueadores de sempre.

This is not a extension that you install to skip ads, this is an extension to make the web remotely sane to browse

Good addon, but it uses a lot RAM and ruins my browsing experience because of it. (I usually have a lot of tabs open).

It's a must-have. Efficient and gets out of the way. Thanks.

Der beste Werbeblocker aller Zeiten! Ein sehr effizienter Blocker! Prozessor-freundlich und bescheiden beim Speicherbedarf!

Excellent alternative to AdBlock and similar extensions, because of lower CPU/RAM usage and better support for 3rd-party lists.
However, by using the latest stable release (v1.22.2) I lose periodically all subscribed lists, so the browser navigation freezes until I disable/reinstall uBlock.
The issue is fixed in v1.22.3.x beta, I hope you'll release them in stable branch asap.
Actually I'm downloading uBlock beta from the official Github repo.

The most powerfull ad-blocker. Installed on all my browsers
