I'm also using 2.0.0.4.  I didn't check the Flash plugin, but did try 
installing the flashplugin-nonfree after it started happening but either 
FF isn't using it or it isn't solving the issue.

What website should I try using to test it, if you know another one that 
is working for you that I could also try?
