Has anyone seen a "lock up" occur on FC6 when running Firefox?

Usually  I'm actively using firefox and suddenly no input capability.  
The entire keyboard is unresponsive as are the mouse keys, though I can 
move the cursor.  This means alt-tab, alt-f1, etc. are a no go.

Most of the URL's I've been on when this happened, were primarily text, 
though who knows what might be going on in the background.  Usually I am 
researching something on a documentation page of some sort though it is 
not limited to that.

I will start running the clock with seconds enabled.  I did have tail -f 
/var/log/messages running  and it showed absolutely nothing.  I start 
vncserver and see if I can get into it the next time....

I'm playing a hunch, right now.  I've installed the nvidia driver for my 
board.  I'll see what happens...
