why is my Firefox disappearing - even after I reinstall it?
Yesterday, the Firefox icon on the task bar turned into what looked like a blank sheet of paper. When I closed Firefox the icon disappeared. I have reinstalled Firefox multiple times and it works until I shut it down - then the icon on the task bar disappears. So I search for Firefox on my computer and click on it and then I get a message which says to install the latest version. Then I get a message to close the other version of Firefox which is running - but there isn't any.

What security software do you have?
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
