Key Takeaways
Full Summary
Microsoft Edge is phasing out support for Manifest V2 (MV2) extensions, which will impact users of ad blockers such as uBlock Origin. Currently, only 58 MV2 extensions are deemed to have meaningful usage, with just three not available on the newer Manifest V3 (MV3) platform.
Starting this month, MV2 extensions will be gradually disabled by default, with users receiving notifications and recommendations for MV3 alternatives. The transition will begin in the Canary, Dev, and Beta channels, eventually reaching the Stable version by the end of 2026.
Enterprise users will see MV2 support end in early 2027. Users seeking ad-blocking solutions can consider alternatives like uBlock Origin Lite or switch to browsers like Opera or Firefox that still support MV2 extensions.
