Hello. For a couple of days my browser has been failing automated captchas when it is hosted by Cloudfare. Any other captcha service works well and lets me go trough.

This is happening on Firefox for Debian Linux 12 (apt). Doesn’t happen on Firefox flatpak and Chromium apt.

What can I do to check further or to give more info?

    Found the problem in my case. I had a user agent changer addon let to fake Chrome 123 on Windows 10. DIsabled it and it worked.

    I was on IceCat, which is using Firefox ESR 115.9.1, and it had the same issue. I had to disable JShelter’s Javascript Shield and Fingerprint Detector.
