firefox does not close properly making reopening later impossible without rebooting computer.
I live in Texas and my sister lives in Georgia. We are both experiencing problems with closing Firefox. It appears to close properly but when I try to reopen later in the day, my computer tells me that it is still running in the back ground and cannot be reopened. I tried upgrading to the latest version but the problem persists. When I go into Task Manager, I can't find an entry for Firefox to close out.

Press CTRL+SHIFT+ESC to open Task Manager, go to the Processes menu, right click on firefox.exe and choose Kill Process.
When you finish a browsing session, go to File | Exit to close it if the problem persists.

If the problem persists in spite of the above steps, try running Firefox in Use Troubleshoot Mode in Firefox. If it functions properly in that configuration, then one of your add-ons is the culprit.
