Supermium is a drop-in replacement for Google Chrome with privacy and usability enhancements, optimized for legacy and modern Windows systems alike. It aims to restore classic Chrome features, as well as to ensure that compatibility with legacy Windows is preserved. Both the 32-bit and 64-bit versions are included for maximum performance and compatibility.

App Notes

Passwords Not Saved Between PCs By Default: Supermium stores passwords in such a way that they are encrypted in a way tied to current PC. While the passwords are not kept or left behind on the PC itself, they won't be retrievable when you move to a new PC. Logging in to Google will save and restore your passwords.

Certificates Not Portable: Supermium has no certificate manager. It uses Windows' certificates manager. So, any certificates you install through the Supermium interface are stored on the current local machine and will not travel with you. Thus, you should not use any private certificates with Supermium except on your own PC.

Some Settings/Extensions Locked Per PC: Supermium locks specific settings to a given PC. Details are included in this post. This behavior is by design by the Chrome team. If you would like this changed, please file a bug with the Chrome team. A suggested workaround is to sign in to Google to restore all settings and extensions.

Note that other portable browsers such as Mozilla Firefox, Portable Edition do not have any of the issues mentioned above. These issues are specific to Chrome and Chromium-based browsers due to Chrome's design and not something we can work around without fixes to the base app by the Chrome developers.
