Why do I have to use task manager to close FF after I exit FF?
I use Firefox close it like normal. If I start it again it will not open and I get and error message "firefox working with other program, try closing firefox".
I then open the task manager, end process, Firefox*32.~.
I thought maybe it could have been a plug so I disabled all plug-ins. Restated FF it went to google/FF home page. I closed firefox at the X. Opened the task manager and it was still running in the end process tab.
