Unlike Google Chrome, Manifest V2 is NOT slated for removal from the Supermium browser.
You may download the latest builds of uBlock directly from the project's GitHub, in the event that it is not obtainable from the Chrome Web Store.
The latest, feature-complete version of uBlock will be made available here if/when Manifest V2 builds for Chromium are discontinued.

Key differences between Chrome and Supermium

The Supermium browser has:

• Aero Glass and Aero Glass-style titlebars instead of Windows 10-style ones


• Turnaround for major vulnerability patches generally less than one week from upstream disclosure


• A functional sandbox for enhanced security


• Custom tab options including trapezoidal tabs, transparent tabs, and outlined tabs


• Many flags from ungoogled-chromium


• Google Sync


• On Windows 7 and up, Widevine CDM support for viewing DRM content


• GDI font rendering, using #force-gdi in chrome://flags


• Persistent dark mode on the browser's UI elements, using #force-dark-mode in chrome://flags


• Support for SSE2-only processors in the 32 bit build


• Manifest V2

It is important to note that Google Chrome is proprietary software, while Supermium, like Chromium is open source.
This means that while similar, Google Chrome's feature set cannot be reproduced perfectly by Supermium.
