Hi dedstrom,

This may be of some importance but upon looking at your plugins I see that you have npmnqmp 989898989877 ' installed.

This is the Move Streaming Media Player 715.5.0.11. I suggest you remove the Move Streaming Media Player from your Add-ons by going to Firefox>Add-ons>Plugins or File>Tools>Add-ons>Plugins

Also uninstall the Move Media Player extension by going to Firefox button>Add-ons>Extensions or File>Tools>Add-ons>Extensions

Does that help? Let me know.
