There isn't 4.5 stars so I'm giving it 4 because it doesn't block some embedded videos and there is no option to block or stop playing them manually. other than that it's a great add on. I'm used to Adblock Plus which has an option to block an element.

One hell of a add-on! great tool for digital self-defense!

AdBlock entfernt und UBlock Origin geladen. Endlich werden Seiten wieder im Turbomodus geladen und das starten des Browsers ist 3x schneller als vorher (wollte schon auf Chrome wechseln).

1.16 broken loading custom filters from "My filters" page in Firefox ESR 52.7.3 - it's a regression that was present before when first WebExtension API version was deployed and then later fixed. Now it's back.
Got back to last 1.15.24 and they loads/work OK.

Absolutely the best add-on to improve your privacy and security - a must have

This extension has worked great for me for a long time. HOWEVER, as of around April 17, 18, 19 or so, a new code from Facebook has caused this extension to prevent all the links in Facebook from working. I hope that in an update (?) of uBlock it will work all right again. I tried disabling a lot of other extensions I use. In this case it was uBlock that was causing the problem. It's a great extension, and I'm betting it will be fixed soon.

This is the best, it's much more than an adblocker, on a larger computer you don't care too much about cpu and memory usuage. So you hit the dashboard and set up all the fanboy and associated tracking / malware / spam and annoyance addons. You'll get warnings if any site has been tagged by them, could be you need to update something like Ccleaner and you're re-directed to a download site. This will warn you of bundleware or tracking, so you're reminded best thing to do is go to the offical site to download. It will at times warn you of sites you're used to, the sort that say you need to download the latest flash, when you already have it. You can simply ignore the warning, and of course tell the download page to exit quickly :-)

¡Exelente!!

Best blocker out there!

Nice

By far the best ad-blocker. Relatively lightweight with the most filters and configuration options. But can you please block ads on Twitch?

Right now is the best. Small, efficient and dont make browser slow.
