Microsoft plans to end support for Manifest V2 extensions in Edge starting this month, following Google Chrome, and for enterprise users in early 2027 (Stevie Bonifield/The Verge)

Microsoft is ending support for Manifest V2 extensions in its Edge browser, following Google Chrome's lead. This change means some popular ad blockers, such as uBlock Origin, will no longer work in Edge. According to Digital Trends, Microsoft is transitioning to Manifest Version 3, a newer extension platform that promises better security, privacy, and performance.

The transition will happen gradually, with remaining Manifest V2 extensions starting to be disabled by default in Canary, Dev, and Beta versions of Edge this month, before expanding to the Stable release in the coming months. Consumer devices are expected to complete the transition by the end of 2026, while enterprise-managed devices will continue to be supported until early 2027, as reported by Digital Trends.

There are only 58 extensions on the Edge Add-On Store with meaningful usage that still use Manifest V2, and only three of those aren't available on the newer Manifest V3 platform, The Verge reports. Users of affected extensions can switch to alternatives like uBlock Origin Lite or use a different browser that still supports Manifest V2 extensions, such as Opera.
