I attempted to join a photography webinar and the system said "The media could not be loaded either because the server or network failed or because the format is not supported. I am running Win 8.1 and have the latest Firefox. Any ideas?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin) always make sure such extensions do not block (wanted) content.

  • make sure your extensions and filters are updated to the latest version
