Why This Matters

Google Chrome's decision to phase out support for MV2 extensions and ad blockers marks a significant shift in browser security and extension management, aiming to reduce vulnerabilities and improve user safety. This change impacts developers and consumers by encouraging the adoption of more secure, modern extension frameworks. It underscores Chrome's commitment to maintaining a safer browsing environment amidst evolving security challenges.

Key Takeaways

MV2 extensions are no longer allowed in any supported version of Chrome, and we are removing support for them and the associated functionality. We won’t be able to provide / maintain this functionality indefinitely due to the complexity and tech debt, as well as the security risks it entails (we’ve actually found a number of bugs that are specific to MV2 lately). Of course, other browsers can continue supporting these if they so desire.
