What Is uBlock Origin
uBlock Origin is a free and open-source content blocker. It is an extension that can be added to Chrome and Firefox. It can block not only some annoying ads on your website, but also some trackers, malicious websites, pop-ups, and more.
What’s more, installing this extension can protect users’ privacy. It will not sell or leak any user data, nor will it participate in the ad whitelisting program. Many users use it to block ads on websites like YouTube to improve the viewing experience.
Why uBlock Origin Is Not Working in Chrome
When you try to add the extension, you will find that the Add to Chrome button is invalid, and the page will prompt you that “This extension is no longer available because it doesn’t follow the best practices for Chrome extensions”.

Chrome has used Manifest V3 as the latest version of the extension platform manifest since October last year. Manifest V3 introduces a number of changes that enhance security and privacy. This includes modifications to the webRequest API.
Many content blockers, such as uBlock Origin, use the webRequest API to intercept content and modify network requests. Therefore, uBlock Origin can no longer be used on Chrome now.
