Supermium is a Chromium-based web browser backported to run on legacy versions of Windows. It uses an abstraction layer to adapt modern engine requirements, enabling contemporary web browsing on older operating systems that lack native support for current Chromium versions.
The project integrates content decryption modules to allow the playback of DRM-protected media streams on unsupported platforms. It also features the ability to disable machine-specific encryption, allowing user profiles to be portable across different hardware installations.
The browser includes a functional sandbox to isolate web processes from the host system and supports the installation of third-party extensions. It provides extensive interface customization, including legacy operating system skins, dark mode, and the ability to modify network headers.
General capabilities cover user data synchronization, privacy controls for cookie retention, and the ability to maintain compatibility with older extension manifests.
