Firefox 137.0.1 and 139.0a1 20250410092904 on Windows 10. Computer has an AMD Ryzen CPU.

The issue is mitigated by the preference change in bug 1959827 which changes media.eme.mfcdm.origin-filter.enabled from 2 to 1.

In addition, I have no luck to reproduce this issue so far, I can watch PlayReady successfully on Canal+.

Should we mark this bug as a duplicate of bug 1958614?

No, I'd like to keep this one open to investigate why PlayReady fails to work.
