Not quite what you're asking for, but Tor users have long complained that Cloudflare basically makes it unusable (asking for complicated captchas on each page of a site, etc.)
I don't even use Tor, just an older Firefox. I'm no longer able to visit any site that uses that Cloudflare "human check". Once I whitelist Cloudflare in uBlock and reload to see the captcha the browser starts to busy-loop. Even closing the tab won't fix that. I have to hard kill the whole thing. I consider it straight malware whatever they do.
Yeah for all the marketing speak on that page about machine learning bot detection, just a browser version and VPN is enough to induce a false positive
I never let Firefox update when it wants to. I update it after Windows does so that everything breaks at the same time. I noticed that as my Firefox version gets two versions behind, I start hitting Cloudflare human test every single site I go to.
Obnoxious. I like the extensions I have, thanks. It's my computer. It's the same fingerprint it was 5 minutes ago, and last week.
