Cannot open Firefox after closing her.

[Dotan Cohen]

Recently, I've found that I'm unable to open Firefox after I close the
program. I close Firefox with the X button on the Title bar. When I
try to open it again, I am confronted with this:
Firefox is already running, but not responding. To open a new window,
you must first close the existing Firefox process, or restart your
system.

I've looked in /.mozilla/firefox/profile but there is no lock file.
Also, typing jobs at the command line shows me no jobs- not even
things that I know are running such as Opera and Kmail.

This problem is reproducable: I reboot, and I can open Firefox.
However, after close, it will not reopen. How can I kill Fx so that I
can restart it, without shutting down?
