Firefox is reported to be running after I close it out.

[William T. Lowther]

I am running Firefox 3.6.24 which was installed with Ubuntu 10.04 LTS.
There are 2 scenarios:
1) I close Firefox, then attempt an Ubuntu shutdown. A message appears (paraphrasing) "Firefox is still running, do I want to shutdown anyway?" This happen ~20% of the time.
2) I close Firefox, and the icon in the bottom tray disappears, but if I click on the Firefox icon at the top to restart Firefox, a message appears "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." Even after the Firefox icon in the bottom tray disappears again, I cannot restart Firefox w/o getting that message. If I then restart Ubuntu, I can re-open Firefox. This happens ~10% of the time.

This is usually caused by stale lock file(s) in ~/.mozilla/firefox/<your-profile-num>default/

That bug is reported as https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/664930

Thanks for the feedback. I checked that bug. The scenario is different
than my experience. I searched my file system for mozilla/firefox/lock
and /.parent and could not locate them.

** Package changed: ubuntu => firefox (Ubuntu)

You have (or maybe just typed) The directory where both lock files are located wrong. Copy/paste these commands:
cd ~/.mozilla/firefox/
cd `ls | grep default`

Now you should be in the right directory.

 OK. I got into the default folder and found lock, but not .parents. I
deleted lock, shutdown firefox, restarted ubuntu, and was able to launch
firefox w/o re-installing it. When closing firefox and shutting down
ubuntu, I still get the message "A program is still running:
firefox-bin" which has below it buttons to "lock screen", "cancel", or
"shutdown anyway" - i.e., no change.

 Update - Resolved
 As of today (or yesterday - not absolutely sure), this problem I
believe has been fixed (by recent updates?).
 In scenario #2, if I close out Firefox and then quickly reopen, the
message box re "Firefox still running" will appear; however, if I close
that message box, a "spinner" progress indicator will appear. Now, if I
wait until the spinner disappears, and then reopen Firefox, it opens
OK.
 Likewise, for scenario #1, if I attempt a shutdown of Ubuntu too
quickly after closing Firefox, I will get the message "A program is
still running: ..". If I close this message, a spinner progress
indicator as above appears, and I can successfully execute a shutdown
after the indicator disappears.
 Evidently, it is necessary to allow Firefox sufficient time to unwind
the websites (tabs) that are displayed in the window or these messages
will appear. The fix is that it is not necessary to restart Ubuntu to
reset Firefox - just wait until the spinner progress indicator
disappears.

Thank you,
Bill

I should add to my post #5 that when I originally posted this problem as a bug, there were no spinner progress indicators that appeared at anytime during the sequence of actions that I had executed. Also, I had a thought at that time that maybe the problem was related to Firefox needing time to "unwind", so I did attempt, on at least 2 occasions, a sequence of steps w/ long delays between steps, but still got the same messages.
