Video files are playing audio without video. It just shows a blank screen. These same videos work just fine in Chrome, thogh.

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).


You can check for problems with current Flash plugin versions and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
  • disable hardware acceleration in the Flash plugin

First, update your Firefox, or go to Mozilla.org for a full install.

Second, Firefox > Add-ons > Plugins. Just above the first plugin there is a link to check that your plugins are up to date. Let us know how you do.

Did both of those things. Videos now have no audio OR video.
