This is an intermitten problem. When closing my Firefox browser by clicking on the Red X button, Firefox appears to close. When I try to restart the browser... I get a message it is already running but it will not resart.  In order to fix the problem, I have to do a Control/Alt/Delete to start the task manager. There I will find Firefox still running at which time I have to end that process of Firefox running in the Process manager.  Once done, Firefox can be started again. This does not happen all the time. I open and close the browser frequently during the course of my time online. If I were to estimate how many times this problem occures I would guess it happens every 1 in 10 times I open and close the browser. Also... in a problem that may be related to this one, I am also experincing the sudden close of my complete Firefox browser when I have multiple instances of tabs open. I click to close one tab.. the entire browser closes. Note: So far I have no problem restarting the browser when this occures. So it may be related to my first problem or not.

This problem did not show up until the last two releases of Firefox came out. Before that this problem I did not occure. Today I updated Firefox to the very latest release. I hoped the problem would be fixed in this latest release but it was not. The previous release was when this problem showed up.
