I believe the setting to turn off the 'greyed out' visual queue stuff
is buried in Compiz somewhere.

The underlying cause is the FF is a very resource hungry application
and your system is not giving it the resources it needs to respond
"normally". Toggling that setting won't change that. Turning off
Compiz itself might help free up some resources (but never tried it).
