Auto User Agent Changer
Automatic user-agent rotation on a schedule
Free · Ad-free · No tracking
Auto User Agent Changer switches your Firefox browser identification (user agent) automatically at configurable intervals. Around 200 common identifiers for Firefox, Chrome, Edge, Opera and Safari on Windows, macOS and Linux are built in. Add your own entries in the settings or via JSON import. For websites that need your real user agent there is a domain blacklist. The popup always shows the active identifier and the countdown to the next change.
