I'd really like some version of E.G. Librewolf configured to spoof the exact SAME information no matter who's using it. Like standard resolution for a 1080p monitor, the same GPU profile, Allow device timing stuff to work but with a fixed profile etc.
Effectively, stop spoofing random data, start spoofing still useful but not for finger printing data.
