Had no problems since months with uBlock origin, great Addon. But since 3-4 days and version 1.16.10 it slows down my firefox completely! CPU use with 50-70 %. Everthing freezes. Youtube sites are not longer usable. I had to deactivate the Addon. And I can see, I am not the only one who has these problems. No reaction here from the authors! I use firefox ESR 52.9.0 (32-Bit) on Ubuntu Studio / Xfce.
Also version 1.16.12 does not solve the thing. So, please fix these problems fast! I need my adblocker. ;) Thanks!

P.S. It was also not possible to update the filters. I tried several times, but no reaction, just "turning circles" symbols.

Blocks more than just ads. For example: on https://www.gls-info.nl it blocks the parcel information. Very annoying as you can't rely on what's shown on a page is "correct and complete"...

Since this automatically?? appeared on my computer where Adblock was, I am unable to connect to certain areas of Meetup.com. Why and how can I fix this?

перестал блокировать говно от Яндекс Директа уже с год, так и не исправился

Difficult to use. Even if an important element on a page is blocked, I can't find any easy way to stop blocking. Should I construct my whitelist? What's the syntax?

Does a great job in keeping things clean. Unfortunately I had to uninstall it because on Firefox v59x, it kept opening the logger in the sidebar whenever I opened the browser. It just got really annoying and I couldn't find the toggle to turn it off. I switched back to adblock+ but If someone could point out my goof, I would happily reinstall.

Seems to "report" to sites it is blocking ads. Some sites show no content, or are broken, or display "disable ad-blocker" warning where adblock plus removes adds AND shows the site correctly. Ublock? Good effort. Not good (enough)

Ha dejado de funcional al 100% no bloquea paginas emergentes como lo hacia antes ,esto esta sucediendo en la edicion 1.15.24 ,si lo arreglar editare el mensaje y pondre mas estrellas ,buscare otro bloqueador mientras se solucionan estos problemas

With a view to integration on an entire computer, I realize that at the first installation of uBlock, the "network request log" panel opens automatically.

Currently I have not yet found a solution so that this panel does not open just after the installation.

KEEPS GOING OFF I HAVE TO REDO IT OVER AND OVEER

After few days youtube in live videos exceeds the 1.5gb and when disabled ublock this fix my problem

Работает через раз, когда блокирует, когда не блокирует.

Up until yesterday, this add-on worked great. Since the latest update, uBlock Origin seems to be preventing Google News links from opening. If I disable uBlock Origin with all of the rest of my add-ons enabled, the Google News links work fine. Yet if I enable uBlock Origin, and disable all of the other add-ons I have installed, the Google News links do not work. When I click on a link, the web page "blinks" off for a split second as if a new page is about to open, but the original page comes back instead, unchanged. However I am still able to open Google News links by right clicking on the link and selecting "Open Link In New Tab". Links on other websites do not appear to be affected. I'm using Firefox 58.0.1 and Windows 10.

I give it 2 stars because I like the way it is set up... but it does NOT block all ads. When on YouTube, ads are still appearing and then on Yahoo mail. At this point, I'm uninstalling and will give it another try down the road.

Worked fine for a few weeks, then made things update too fast to read, especially bad on Facebook

Very buggy. A lot of websites break. There were too many already, but now lets facebook trip too. That does it.

Of course, you can disable uBlock for sites it breaks, but what's the point of having it if you can't enable it?
