Official Windows Registry hack extends uBlock Origin support on Google Chrome, Edge
...
For those who want to keep using Manifest V2 extensions like uBlock Origin in the foreseeable future, one way to do so is to migrate to Mozilla's Firefox, which has no plans to drop MV2 support any time soon. The Gecko-based browser recently said that it wants to extend the support for Windows 7, 8, and 8.1 further.
If you want to stick to Chromium, an official Registry hack exists that allows extending the support for MV2 add-ons with the help of the "ExtensionManifestV2Availability" policy that is designed for enterprises. Enabling the policy allows an extended year of support for MV2 add-ons till June 2025.
