Videos not playing in Firefox
Recently got a new computer and most websites will not play videos. Youtube works, Netflix does not (Netflix Error F7701-1003), Reddit video player does not, https://www.pexels.com/videos/ doers not.
I have tried troubleshooting mode, reinstalling firefox, have made sure it is up to date, cleared cache, and I'm not using any addons.
These videos work in Edge so I don't think it's my drivers (checked that they are up to date).

See:
Make sure Firefox isn't set to run in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).
- Settings -> Privacy & Security
Firefox will: "Use custom settings for history" - remove checkmark: [ ] "Always use Private Browsing mode"
You can toggle DRM off/on to see if that makes Firefox (re)load DRM components.
- Settings -> General: Play DRM

You can possibly check the XHR requests in the Browser Console if this doesn't work.
