While watching netflix, I randomly get error code F7361-1253 which prevents the video from playing. Can happen at any random time while watching. I have had firefox for years and have only got this issue in the past few months. It does not happen on other browsers like chrome. I have tried disabling all extensions and troubleshoot mode, doesn't fix it. I didn't change any firefox settings since this started happening. DRM is enabled, widevine is the latest version, so is firefox, fully updated. I am using Windows 11 Home, 10.0.22631 Build 22631 These are the warnings I got in the console as soon as the netflix error pops up: Cannot play media.
