About this tag
Manifest V2 refers to the previous extension framework used by Chromium-based browsers like Microsoft Edge. Discussions on WindowsForum cover the transition to Manifest V3, which introduces the Declarative Net Request API and stricter content blocking rules. A notable incident involved uBlock Origin being temporarily replaced by uBlock Origin Lite in the Microsoft Store due to an upload error, highlighting the impact of the MV2 to MV3 shift on ad-blocking extensions. Users and developers are testing these changes in Edge Beta and Stable channels, with Microsoft emphasizing privacy, security, and performance improvements. The tag covers real-world effects of the extension API migration, including compatibility issues and recovery steps for affected users.
