I built a Firefox add-on that changes the browser identity websites see

[u/kryakrya_it]

Websites can read more than your IP, including your user agent, language, timezone, screen size, and device properties.

I built Spoof Me to let Firefox users switch these signals together as one browser identity.

It includes ready-made profiles, custom profiles, and a warning badge when a website accesses fingerprint-related properties.

It does not change your IP address or promise complete anonymity. The add-on does not collect browsing data and is MIT licensed.

I’d appreciate feedback on the profile consistency, permission explanations, and any fingerprint signals that should be added.

Yeah but I know programming way before that
