I attempted to open a new window from the Firefox icon but nothing happens. I then went on browsing and closed Firefox but was later unable to open it. I checked processes and it was already running but there was no window displayed. I am running Windows 7 Professional. This is repeated any time I already have the browser open and wish to open a second instance.
