The story so far
Microsoft is transitioning its Edge browser extensions to Manifest Version 3, a move that will effectively disable older ad blockers and similar add-ons. This shift aligns the Edge ecosystem with Google Chrome’s architecture, which has already implemented the transition. The Windows Blog frames the update as an effort to move the browser's extension ecosystem forward.
The Verge, Digital Trends, and Neowin emphasize that the policy change will specifically render existing ad-blocking tools, such as uBlock Origin, non-functional. While Thurrott.com confirms the transition is scheduled for this year, coverage provides limited clarity on specific implementation timelines or transition windows for individual users. Public discourse acknowledges the technical shift toward Manifest Version 3, yet coverage does not specify if Microsoft plans to offer compatibility patches for legacy extensions.
The exact date for the full lockout of non-compliant add-ons is not explicitly stated in current reports.
