After having the error F7121-1331 when trying to watch a Netflix video, I found that the privacy.resistFingerprinting was the source of the problem.

You can keep this option and change the parameters in about:config

  • privacy.resistFingerprinting.testGranularityMask : 4
  • privacy.resistFingerprinting.exemptedDomains : *.netflix.com, *.nflxext.com
