MICROSOFT is retiring Manifest V2 (MV2) extensions in Edge, affecting many popular privacy tools. The transition to Manifest V3 (MV3) is aimed at enhancing security and performance, as 95% of MV2 extensions already migrated to MV3. Starting this month, warnings will be displayed to users of MV2 extensions, which will be disabled by default in coming months. This change particularly impacts privacy tools like ad blockers that modify requests and responses.
Developers face challenges due to limits on rules in MV3, but companies like Malwarebytes have adapted their tools, such as the Browser Guard, to comply with the new standards.
