TL;DR
Microsoft Edge is set to disable support for older ad blocker extensions, similar to Chrome’s recent move. This change will impact users relying on legacy ad blocking tools. The development is confirmed and scheduled for upcoming updates.
Microsoft Edge will soon block support for older ad blocker extensions, aligning with Google’s recent policy change in Chrome that restricts legacy ad blockers. This move affects users relying on extensions that have not been updated to comply with new standards. The change is scheduled to roll out in upcoming updates, marking a significant shift in browser extension policies that could impact online ad blocking practices.
Microsoft confirmed that support for legacy ad blocker extensions will be phased out in Edge, following Chrome’s lead, which implemented a similar restriction in early 2024. The change is part of a broader effort to improve security and performance by discouraging extensions that do not meet current standards. Users will no longer be able to install or run older ad blockers that haven’t been updated to support Manifest V3, the latest extension framework.
Sources close to Microsoft indicate that the update is scheduled for release in the next major version of Edge, expected within the coming months. The company has not specified a precise date but emphasized that users should update their extensions or switch to supported alternatives before the change takes effect. This move is expected to impact a significant portion of users who rely on legacy ad blockers for privacy and browsing experience.
Implications of Edge’s Adoption of Chrome’s Extension Policies
This development matters because it signals a shift towards more restrictive extension policies across major browsers, potentially reducing the availability of certain ad blockers. For users, this could mean losing access to popular legacy extensions and needing to find updated or alternative tools. It also reflects a broader industry trend prioritizing security and performance over extension flexibility, which could influence future browsing experiences and privacy practices.

Background of Extension Policy Changes in Major Browsers
In early 2024, Google Chrome announced it would block support for extensions built on Manifest V2, the older extension framework, encouraging developers to transition to Manifest V3. Chrome’s policy aimed to improve security and reduce extension-related vulnerabilities, but it also led to the discontinuation of many popular ad blockers that could not be updated in time.
Microsoft Edge, built on the Chromium engine, announced it would adopt similar policies, aligning with Chrome’s standards. This move follows a pattern among Chromium-based browsers, emphasizing security and performance but raising concerns about the impact on ad blocking and user privacy.
“We are aligning our extension policies with industry standards to enhance security and performance. Users are encouraged to update their extensions accordingly.”
