Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

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.
