..We’ve had a lot of questions about Chromium’s transition to Manifest V3, and specifically how your Opera experience with extensions and functionality like ad blocking will be affected. Good news: We plan to continue supporting Manifest V2 extensions in Opera independently of what will happen to other browsers. This means that users of Opera’s browsers should expect to continue to use non-graded versions of their favorite ad blocker extensions. ..
* With Firefox, Brave and now Opera there are options for those who wish to continue using Manifest v2 extensions.
