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.

You are the best Raymond Hill! In this relentless digital war for our data, uBlock Origin remains the only wall that doesn't crumble. 1,200+ blocks in a single session is not just a statistic; it’s our right to exist online without being harvested. Thank you, for your work, for the unpaid excellent work, unwavering idealism. 5 stars are simply a formality for a masterpiece of privacy. Pure, unadulterated perfection! And by extending this philosophy to the DNS level, the protection is now absolute. No tracker survives, no data is harvested. You haven't just built a tool; you've built a sanctuary of privacy. Thank you for the 'Increase' in our freedom!

Google has made it so you can't watch youtube videos if you have this program active on your computer. By active I mean running at all even if it is disabled for youtube. If you go to settings and turn it off there so that it is not active for any websites then you can use youtube pretty reliably otherwise you will have buffering problems and slow videos.
