What to do if your Chrome extension is no longer supported

Are you seeing a This extension may soon no longer be supported or a This extension was turned off because it’s no longer supported message when you try to use your favorite extensions in Chrome? That’s likely because it was built using the older Manifest V2 extension framework. Thankfully, you can get your ad blocker back in 30 seconds, just by switching to Brave.

To make the switch, follow these 3 easy steps:

  1. Download Brave for desktop (macOS or Windows) or mobile (Android or iOS).
  2. Follow the prompts to complete the install.
  3. Once Brave opens, click the button to import browsing history, saved passwords, and other extensions from Chrome.

That’s it! You can now browse like you’d expect to with Chrome + an extension-based ad blocker like uBlock Origin.

What is Brave?

Brave is a user-first, private browser with a built-in ad blocker called Shields. Brave Shields block creepy ads and trackers, cookies and pop-ups, fingerprinting and more on any page you visit. And it does this by default, no extensions required.

Brave has 70 million users worldwide, with hundreds of thousands more downloading everyday—most of whom are switching from Chrome. Brave is also built on Chromium, the same open-source browser engine that powers Chrome, Edge, Opera, and Vivaldi. This means Brave will have a familiar feel and navigation, but with the added benefit of a built-in ad blocker and tons of great features you won’t find anywhere else.

This Chromium foundation also means you can easily import settings as you migrate from Chrome to Brave.

What is Manifest v2?

This framework—which Google pushed extension builders to use—has been the longstanding foundation for hundreds of browser extensions, including most available on the Chrome Web Store today. However, Google recently began the rollout of Manifest V3, and dictated that all extensions available in the Web Store must be built on this framework going forward. Manifest V3 will be fully released by June, 2025.

For most extension makers, it’s difficult to convert or migrate Manifest V2 to V3. This means most Manifest V2 extensions will simply be deprecated, and some replacements may (or may not) take their place.

As any regular Chrome user knows, Google’s browser has no native ad blocker. So these Chrome ad block extensions have been an integral part of their browsing experience.

Thankfully, you can easily switch to Brave, which allows you to continue using some Manifest V2 extensions. And, more importantly, Brave has a built-in ad blocker that means you won’t need an extension-based ad blocker at all.

Will Manifest V2 extensions work in Brave?

Brave has committed to continue supporting some Manifest V2 extensions, specifically AdGuard, NoScript, uBlock Origin, and uMatrix. But as stated above, the value of Brave Shields means ad block extensions won’t be necessary in Brave.
