Opera Software released Opera One R2 this week. The new stable version of Opera comes with a large number of new features and changes.

This includes the new dynamic themes feature, tab splitting and recent tab highlighting, more AI functionality, and something that is easily overlooked in the long post on the Opera Software website: continued support for Manifest V2 extensions.

Here is what Opera says about extensions support: " In addition to that, Opera R2 will continue supporting Manifest V2 extensions, allowing you to continue using your favorite ad blocking and privacy-enhancing extensions just like before".

The post links to another one on the Opera website that provides additional details.

Opera plans to support Manifest V2 extensions independently of the development of Chromium, the source of Google Chrome and other browsers.

This means, that Opera users may continue to run and install Manifest V2 extensions, like uBlock Origin, in the web browser.

Now, the post is not very clear on the details. Opera Software mentions that it plans to contact extension developers to "determine the best and safest way forward".

Continued support would be remarkable at this point, as Google will remove code from Chromium next year. Up until then, policies exist to keep on using Manifest V2 extensions in Chromium-based browsers.

The removal of support of Manifest V2 has already started in Google Chrome for users who have not set the policies.

Up until now, only Brave Software announced that its browser, Brave, would support a few Manifest V2 extensions going forward.

Opera's commitment to all Manifest V2 extensions, if it is feasible for the company, ensures that users can continue using their favorite extensions and new Manifest V3 extensions. This would work similarly to Firefox, which also supports both Manifest V2 and V3 extensions.

Opera Software has one advantage over Brave Software and most Chromium-based browser makers (with the exception of Microsoft and Google). It operates its own extension store. While Opera users may also download and install extensions from the Chrome Web Store, users may also download and install extensions from the company's own store.

Brave Software does not operate its own store, which is probably the main reason why it decided to support only a few extensions. Google will remove Manifest V2 extensions from its web store next year when the policy option runs out.

Closing Words

Two Chromium-based browsers will continue to support Manifest V2 extensions by mid-2025 at the time of writing. That's Brave, which supports only a few, and Opera, which plans to support all of them.

It remains to be seen how this will work out and if other browser makers are also jumping on the bandwagon that separates them from main Chromium in a key aspect.
