I've noticed a significant bug while using uBlock Origin on Facebook. In Facebook Groups, the "New Posts" sorting feature stopped working correctly, and many posts (especially text-only ones) were not showing up at all in the feed. Even though the sidebar indicated new activity, the main feed remained broken or stuck.
After some troubleshooting, I disabled uBlock Origin for Facebook, and the issue was immediately resolved-all posts appeared and the sorting worked again. It seems some cosmetic filters or scripts might be over-blocking essential Facebook Group elements.

Thank you for the great uBlock Origin extension. If configured correctly, I use four filters: EasyPrivacy, AdGuard/uBO – URL Tracking Protection, uBlock filters – Badware risks, and Malicious URL Blocklist. This allows me to block tracking without blocking ads, reduces device load, and doesn’t interfere with content creators earning from advertising.

I highly recommend it but i would very appreciate that there is an option to add a password option for editing the settings. I block certain websites but it's almost 2 clicks easy to disable it. This would prevent a child to have access to websites for exemple

If you are not using this you are missing out. It simply the best ad/tracker blocker. Once you have started using this, the internet becomes unbearable without it. Thank you so much to the dev team! Can't recommend this enough.

In my opinion and experience this is the best free ad blocking service available. Very effective with little to none CPU load.

The GOAT Firefox add-on. It's not just for blocking ads, it also goes a great job of blocking all sorts of cruft that has turned the Internet into a nightmare to use e.g. floating video windows, chatbots etc. I will never use the Internet without uBlock Origin ever again.

Unusuable. There are no instructions of any kind. The UI is not any standard kind. Everything is hidden behind some inscrutable icon. All I want is a way to say "block this page", or to add a URL to a block list, but despite the vast multitude of icons and menus leading down endless rabbitholes, there are no options to block this page, or to add a URL to a block list, that I can find. Neither is there any provided blocklist, or info on where to find a good blocklist. This is possibly the worst user interface I've ever seen in nearly 50 years of using computers every day. It's like it was made by ancient Egyptians.

I can no longer use the internet without this. Websites run so much faster and are less cluttered now that there aren't 100 video adds playing at once. What is even better than the add blocking is the fact that you can block anything you want. I use this feature constantly. I've remove so many AI "features" and messages telling me I should get the premium version of whatever I'm using.
With this extension, everything I see on the internet is only what I intended to.
Absolutely incredible. I can't live without it.

It's good, but the only con is that it removes subtitles at youtube

YouTube playback is delayed.

This is a must-have extension, makes browsing so much faster and cleaner. It speeds up browsing so much, even with all the filters enabled, it still has a significant speed gain. I finally don't have to deal with al those ads. It also blocks other trackers in the background so they don't collect info about you. It almost never breaks a site, and even when it does, it is easy to fix. Would recommand.

The primary reason I'm sticking with Firefox. It's hard to express how grateful I am for this add-on. Thank you so much for the hard work.
