Unfortunately, Cloudflare and other protections will keep working even less than they used to. I have started to not use Cloudflare protected websites because they don’t work with Firefox. But that is a fight I am going to lose.
Cloudflare and their crappy widget has done a disservice to the Internet and humanity. They really do need to come up with something else.
I run exclusively Firefox over known mullvad VPN endpoints and I never have any issues with cloudflare or its captcha.
I guess you don’t have fingerprint resist on:

Symptoms? Is it limited to when a site has Cloudflare's more aggressive protection turned on? I haven't noticed any problems I've attributed to Cloudflare, and I use Firefox exclusively.
The only symptom is that captcha never completes.
I have more restrictive protections on. If you use just loose settings, it completes, but advanced fingerprint protection, for example, breaks captcha completion.
This is very known issue.

This matches my experience as well. As a FF user, I very occasionally encounter problems, but these don't seem to be correlated to their using CF protections. Much more often I find sites broken that rely on cloud domains with bad reputations, which my DNS filters block.
I was actually wondering if the stuff that Mozilla's talking about here will be used by bad bot people to try to circumvent CF's abuse protections. As I recall from when I was working with them, CF's service relies in part on being able to identify botnet attacks by doing its own fingerprinting.
I'm sorry whatever problem you've run into, but it's definitely not true that no cloudflare protected websites work with any Firefox. You've run into something more specific, I guess.
