Dear Sir or Madam, I am using GNU IceCat which I enjoy using. Unfortunately I can't play videos on news websites, etc. I get an error message about codec. Operating System is Fedora 33. I have disabled all extensions that were default except HTTPS Everywhere. The only other extension I am using is uBlock Origin which I am familiar on how to use. I would appreciate any help. Please keep any instructions simple as I am a novice on software, etc. I hope to hear from you soon. Yours sincerely Paul
