What version of flash and silverlight do you have, and does this happen in safe mode? http://support.mozilla.com/en-US/kb/safe+mode.

Flash: 10.1.82.76
Silverlight 4.0.50524.0

Both are up to date according to http://www.mozilla.com/en-US/plugincheck/ .

I tried the safe mode, and it did not happen. However, as I have said before, the bug occurs randomly and I might simply have not tried long enough.

It seems that having Windows Media Center opened makes this glitch more likely to happen.
