A VPN changes your IP address, but websites can still observe signals such as your timezone, language, screen resolution, user agent, canvas output, hardware details, and other browser properties.

I built Spoof Me to let users control these fingerprinting signals through separate browser identity profiles. This article explains what a VPN does not hide, how browser fingerprinting works, and the approach used by the extension.

I would appreciate technical feedback on the fingerprinting methods covered, possible bypasses, and anything important that the extension may still be missing.
