TL;DR
Microsoft Edge is set to disable support for older ad blockers, following a move by Chrome. This change aims to improve browser security and performance but may impact users relying on legacy extensions.
Microsoft Edge is preparing to restrict support for older ad blockers, aligning with Google Chrome’s recent policy change. This move, confirmed by Microsoft, aims to enhance browser security and performance but could affect users who rely on legacy extensions.
Microsoft announced that, starting with an upcoming update, support for certain older ad blocker extensions will be disabled in Edge. The change is designed to prevent extensions that no longer meet security standards from functioning, similar to Chrome’s policy introduced earlier this year. Microsoft officials stated that the update will primarily impact extensions that do not adhere to the latest extension development guidelines, which prioritize security and user privacy. The update is currently in the rollout phase and is expected to be fully implemented across all supported versions of Edge within the next few weeks. This policy shift is part of Microsoft’s broader effort to improve browser security and reduce vulnerabilities associated with outdated extensions.Users who rely on older ad blockers are advised to update their extensions or switch to supported, compliant versions. Microsoft has also indicated that developers of legacy extensions will be notified and encouraged to update their products to ensure continued support.
Implications for Ad Blocker Users and Developers
This development signifies a tightening of extension support policies in major browsers, aiming to improve security and reduce potential attack vectors. For users, it means that some familiar ad blockers may cease functioning unless updated. Developers will need to adapt their extensions to meet new standards, which could accelerate the decline of legacy ad blockers and influence the future landscape of browser extensions. The move underscores ongoing efforts by browser vendors to prioritize security and user privacy, but also raises concerns about the accessibility of ad-blocking tools for certain users.ad blocker extension for Microsoft Edge

Microsoft’s Extension Support Policy and Chrome’s Similar Move
In early 2024, Google Chrome announced it would block support for older ad blocker extensions that do not meet new security standards, citing concerns over extension vulnerabilities. Chrome’s policy led to widespread updates from extension developers and a shift in the ad-blocking ecosystem. Microsoft Edge, which shares a Chromium base, is now following suit, with official confirmation that support for outdated ad blockers will be phased out. Historically, Edge has supported a broader range of extensions, but recent security updates have prompted a reevaluation of extension support policies. The upcoming change reflects a broader industry trend toward stricter extension security requirements, aiming to protect users from malicious or poorly maintained extensions.“We are committed to providing a secure browsing experience and will be updating support for extensions that no longer meet our security standards.”
