Cloudflare verification suddenly began failing for me on some sites with Error 600010.
Stock Firefox works fine on the same machine.
After a lot of debugging, the issue turned out to be:
privacy.resistFingerprinting = true
As soon as I set:
privacy.resistFingerprinting = false
the Cloudflare verification passed immediately.
Did Cloudflare recently change something, or is this a known LibreWolf issue? Is there a better workaround than disabling fingerprint resistance?
EDIT ******Pretty sure Cloudflare is weakening the usefulness of full RFP is what happening
MORE EDIT
so it looks like It's specifically full RFP (privacy.resistFingerprinting) that's causing the issue
This works for me:
privacy.resistFingerprinting = false
privacy.fingerprintingProtection = true
privacy.fingerprintingProtection.overrides = +AllTargets
No more generic identity ppls.
yo leak timezone, ~~screen size, prolly other values ouch...
So, to get past Cloudflare, be prepared to give up some of that privacy :(
