uBlock Origin has received praise from technology websites, and is reported to be much less memory-intensive than other extensions
Manifesto
• The user decides what web content is acceptable or not in their browser.
• The uBlock Origin 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 Origin's sole purpose is to give users the means to enforce their own choices.

View alluBlock Origin was added to AlternativeTo by on Apr 25, 2015 and this page was last updated Jan 21, 2021. uBlock Origin is sometimes referred to as uBlock0.
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.

Wladimir Palant has made himself untrustworthy with his inane "acceptable privacy violation" defaults.
3rd party ads sell privacy for profit: this is ALWAYS UNACCEPTABLE.
ublock origin is the only remaining adBLOCK project with a focus on BLOCKING and safeguarding PRIVACY
There is no viable alternative to uBlock Origin.
Doesn't lag,Doesn't show promoted ads [ So better than AdBlock ],restricts viewing sites with malware or crapware downloads and that stuff. This is kind of my first line of defense yo. Perfect. Also its much more lightweight than Edge.
Yeah, I agree. Much better than ABP and ghostery. Both are slimos. I also like that it is open source. Can check out stuff.

Uses the same code as Adblock, but without the ads whitelist and less memory. Need I say more.
Uses improved code
