For about a month already (GitLab issue) Cloudflare blocks browsers with privacy.resistFingerprinting = true (Tor has in enabled by default, and AFAIK LibreWolf, too).
It seems there is no official reply yet from GitLab (although this not only affects GitLab but many websites) or Cloudflare.
Also from the issues (Mozilla tracker) and linked discussions it looks like this was not an intentional move by Cloudflare.
I think it’s strange that we haven’t seen any news on the topic, and seemingly no reaction from website owners, or did I just miss them?
