I opened it in Firefox and Librewolf just to see how the information sent was different. Librewolf obfuscated the following which Firefox disclosed:

Time zone

Monitor resolution

GPU used

Also, the Firefox one said I moved my cursor such-and-such times, while the Librewolf one said my finger moved such-and-such times. Must be related to hiding what screen I'm using. I'm on desktop.

    Firefox on mobile obscured GPU.

    "Your browser masked your graphics processor. Firefox and Safari have started returning generic strings — "Mozilla", "Apple", "or similar" — instead of the real renderer. The fact that yours did so tells us, with reasonable confidence, which browser you are running. The mask is also a fingerprint."
