why is my Firefox disappearing - even after I reinstall it?

Skrevet

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.
