Try to disable Windows Media Foundation by setting these prefs to false on the about:config page.

• media.directshow.enabled = false
• media.windows-media-foundation.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Thank you it worked!
