Microsoft Edge will soon discontinue support for Manifest V2 extensions, marking a significant shift in the browser’s add-on ecosystem. This decision mirrors Google Chrome’s earlier transition away from the older extension platform, affecting popular tools like uBlock Origin that rely on the outdated technology. According to Microsoft’s announcement, only a small number of extensions on the Edge Add-On Store actively use MV2, with just three lacking modern alternatives.
Users currently relying on incompatible ad blockers will need to adapt their browsing habits. Microsoft recommends switching to updated versions such as uBlock Origin Lite, which operates on the newer MV3 framework. Alternatively, users dissatisfied with Edge’s direction have other browser options available, including Opera and Firefox, which maintain ongoing support for legacy MV2 extensions.
The company plans to roll out these changes gradually, beginning this month across its development channels before expanding to all consumer users by year’s end. Affected users will receive notifications in advance, allowing them time to select compatible replacements. Enterprise users will experience a later deprecation timeline, with full transition expected in early 2027, ensuring businesses have adequate preparation time to implement necessary changes across their organizations.
