I am running Windows 7. Sometimes when I try to open Firefox, I get a message that says Firefox is already running. I check task manager, no Firefox running. Have to log off then back on.
Windows 7, HP Pavilion dv3, Firefox version 4.0.1 (new 5 version freezes up often, had to use earlier version)

1) You should update to Firefox 7.0.1
2) Is plugin-container.exe listed?
I rolled back to version 5 and then 4 because version 7 was slow to load and would freeze up often. The original problem started before I upgraded to version 7. How do I check to see if plug-in container.exe is listed?
Open Task Manager and look for an entry by the name of plugin-container.exe.
See "Hang at exit":
The plug in is there
