Comment summary: uBlock Origin is widely praised for being lightweight, effective at blocking ads, and protecting user privacy without selling whitelist space for profit. Users appreciate its configurability, open-source nature, and community support. Criticisms include some limitations in blocking certain types of ads and compatibility issues with Safari. While it outperforms other ad blockers regarding resource efficiency, some users highlight potential risks with highly privileged extensions.

The good • I love it. It is owned and supported by a friendly community. Not a corporation. More secure because its code is publicly available for review and contributions on GitHub at https://github.com/gorhill/uBlock • Easy to use. With both basic or advanced modes. • Lightweight on memory and CPU resources • More than 12 million users. Including 3.8+ millions users on Firefox and 8.9+ millions users on Chrome • Clear Manifesto: ......• The user decides what web content is acceptable or not in their browser. ......• The uBlock project does not support Adblock Plus' "Acceptable Ads Manifesto", because the "Acceptable Ads" marketing campaign is really the business plan of a for-profit entity. ......• Users are best placed to know what is or is not acceptable to them. uBlock's sole purpose is to give users the means to enforce their own choices. • Lots of features • uBlock Origin has a better track record at fully protecting your privacy, than AdBlock Plus (ABP). There is a controversy around ABP and its related for profit corporation trying to monetize ABP via ad whitelisting. Which means that corporation sales your privacy for profit :( Source at https://en.wikipedia.org/wiki/Adblock_Plus

The bad • Confusion with the names. Between "uBlock Origin" and "uBlock". For those not familiar with those names, uBlock Origin is better than uBlock. Mostly because as of May 2017 Ublock Origin is still actively maintained and updated. Source at https://en.wikipedia.org/wiki/UBlock_Origin Compare to uBlock which as not been maintained and updated for more than 2 years, since 2015, and is trying to monetize an open source project.

People who want adblock but don't do any research wind up with AdBlock Plus. Those that do a little digging will find that uBlock Origin is the best in pretty much every aspect.

This extension is a straight up necessity on every browser I use. The only thing that would make me recommend uBlock origin more is if it came out of the screen and kissed me in the lips every time i blocked an ad.

As it stands as a monument in the current times of the internet. A helping hand for those who wanted to have a cleaner internet experience. And proven for years to be one of most effective ways to serve its purpose. Facing lots of challenges to fight with.

For me this ublock origin deserves a statue on the internet.

ublock worked quite well for a while. Then Google blocked them. And what did they do? NOTHING. MAJOR bitch energy. Can't easily download a .crx, no easy way to install - they just gave up. Honestly? They deserve to go extinct. Pathetic, really pathetic.

uBlock Origin is still available on Google Chrome, but with Manifest V3, the capabilities are limited (Google's fault). You can just use another supported web browser like Firefox if you want to keep using uBlock Origin with full blocking capabilities.

What is uBlock Origin?

An efficient blocker add-on for various browsers. Fast, potent, and lean.

uBlock Origin is NOT an "ad blocker": it is a wide-spectrum blocker -- which happens to be able to function as a mere "ad blocker". The default behavior of uBlock Origin when newly installed is to block ads, trackers and malware sites -- through EasyList, EasyPrivacy, Peter Lowe’s ad/tracking/malware servers, Online Malicious URL Blocklist, and uBlock Origin's own filter lists.
