I get this message only on Linkedin.com videos: "The media could not be loaded, either because the server or network failed or because the format is not supported.", videos on other websites work perfectly fine. This happens only on firefox. Linkedin videos work fine on other browsers. I don't have any adblock plugins installed. I use Windows 10, Firefox 95. I checked other forums for similar problems, doesn't work for me. Also, I have no problem with videos on Linkedin when I open it on Firefox for iOS.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Here's a link to a Linkedin Video https://www.linkedin.com/posts/ubisoft-toronto_ubisoft-toronto-is-hiring-for-splinter-cell-activity-6877299131895959552-thyD

I have cleared cookies an cache, I'm not blocking anything but the problem still persists. Just to be clear, this problem is specific to linkedin.com on Firefox Browser on Windows Laptop. Linkedin videos play fine on other devices on firefox, and other browsers on the Windows Laptop.

I have several versions of Firefox and had no problem.


Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
