Microsoft Edge is set to fully remove support for Manifest V2 extensions by the end of 2026, aligning with Google Chrome's standards, which will significantly impact the functionality of ad blockers like uBlock Origin. The transition to Manifest V3 involves replacing persistent background pages with service workers, enforcing a limit of 30,000 filter rules, and banning remote code execution, which has raised concerns among privacy advocates about reduced user control and a potential increase in tracking. While Microsoft argues that these changes are aimed at enhancing security and performance, many users are left with limited options, prompting a shift toward alternative browsers like Firefox, Brave, or Vivaldi that still support legacy extensions. As the browser landscape evolves, users must adapt to these changes or face the consequences of losing access to important privacy tools

Microsoft Edge is accelerating its deprecation of Manifest V2 extensions, targeting full removal by the end of 2026 to align with Google Chrome's Chromium standards. The transition replaces persistent background pages with service workers, caps filter rules at 30,000, and bans remote code execution, effectively killing uBlock Origin and forcing ad blockers into reduced-functionality modes. While Microsoft defends the move as a security upgrade, privacy advocates argue it creates a backdoor for trackers and strips users of browsing control, leaving those who rely on legacy tools with no choice but to switch to Firefox, Brave, or Vivaldi.
