Firefox shows as open on the task bar with a small screen but will not expand or display full screen.
I open Firefox and it shows as open on the task bar. I hover off the icon and it shows the Firefox screen but will not expand past that. I've uninstalled it and reinstalled it and updated it to no avail. I cannot open it in any screen except when I hold my mouse over it.
