I have FF-156 (snap) on *buntu 26.04, and if I use a custom user agent for privacy reasons, I no longer have access to some websites because Cloudflare thinks I am a bot. Somehow, Cloudflare is able to detect, that I am not running FF on Windows, and that suggests that some sort of fingerprinting defeats FF security settings.
Steps to reproduce on Linux: Update FF to latest version (156.0.Something), create a new profile, and go to "about:config", search for "general.useragent.override" and set the string value to "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:156.0) Gecko/20100101 Firefox/156.0". Go to "https://www.raspberrypi.org/forums/viewforum.php?f=63" and you will enter a "Verifying that your are a human" loop.
How can Cloudflare detect this change, and what is there to do about it?
