Chrome’s newest v150 update, rolled out yesterday, has abruptly disabled all support for Manifest V2 extensions, effectively ending their functionality across the browser.
With no official path to restore MV2 support in v150, the only practical workaround left is to roll back to a prior Chrome build that still honors the older extension format.
Of course, downgrading introduces serious security concerns and is not endorsed by Google, as it exposes users to unpatched vulnerabilities.
To keep Chrome from auto‑updating to v150, you can disable the two Google Updater services. This prevents the browser from fetching the latest build and keeps it locked at the previous version, thereby preserving MV2 extension functionality.
While this method can buy you time, it is not recommended. Only proceed if you are fully aware of the risks and are comfortable accepting the associated security implications.
The guidance presented here offers a practical strategy for users to extend the window of time available to evaluate alternative solutions, ensuring a smoother transition when changes arise.
❓ Frequently Asked Questions (FAQ)
Why did Chrome v150 disable support for Manifest V2 extensions?
Chrome v150 removed MV2 support as part of Google’s plan to accelerate the transition to the newer Manifest V3 framework, which offers improved security, performance, and privacy features. The change is a deliberate step to phase out legacy extensions that no longer meet the updated security and performance standards.
How can I keep my MV2 extensions working after the update?
The only practical workaround is to roll back to a prior Chrome build that still supports MV2. You can do this by disabling the Google Updater services to prevent automatic updates, then manually install the older Chrome version. However, this approach is not endorsed by Google and should only be used temporarily while you evaluate or migrate to MV3 extensions.
What are the risks of rolling back Chrome to a previous version?
Rolling back exposes your system to unpatched security vulnerabilities, malware, and compatibility issues. The older build will not receive security patches, leaving you vulnerable to exploits. Additionally, disabling automatic updates can prevent you from receiving critical bug fixes and performance improvements, potentially compromising overall browser stability.
