I use uBlock Origin in addition to uMatrix. uBO primarily replaced 5 addons I used in the past. But even if it would've only replace one addon out of those 5 I'd have switched. Never regretted it.

Best Blocker so far! Really good work!

It doesn't slow my browser.

Ad-blocking done right.

非常有效 使用上沒有任何干擾

This extension blocks ads superbly. I used another extension for years, but the lower resource utilization and straightforwardness got me to move to uBlock Origin. Many webpages can somehow detect that ads are being blocked; I wish there was a workaround for this. But this does an excellent job blocking the ad-scourge of the Internet.

Всё супер!

Getting more and more ads these days

Diese Erweiterung isteinfach prima, und ich würde sie jedem empfehlen. Ich bin durch Zufall draufgekommen, hatte vorher gar nicht gewusst, dass es sie gibt. Vielen Dank "to whome it may concern"!!!

Ublock Origins not working properly on face book since the last 2 Firefox updates.
Keep getting "Sponsored posts" on the right side of the page.. If I move the news feed column down, The "sponsored post" pops back up. Just had it happen again. Randy, how do we reply here? I have latest Firefox, 57.0.1

The best.

本質的です

After the recent Firefox update I've started seeing ads on random sites from time to time. And today this shit has unfortunately reached my primary social network, vk.com.

started some time ago to not work on the first page when browser is openend (cookie warning etc not being blocked) on reload of this page it all works fine.
