I have noticed a weird window when I right-click on the firefox icon, it seems to be the help site for an app I have recently began using (TaskHeat from Eyen), but when I click on it no window actually appears, and nothing shows when I select "show all windows". When I click "new window" I am able to open a firefox window, but it still shows the other weird window when I check in "window" on the taskbar, or right click the firefox icon. It just feels really suspicious that it's just sat there and that windows won't load unless I select new window. I have tried lots of things- force quit, zoom, changing resolution settings, uninstalling and re-installing firefox, logging out and back in, updating software; but none of them have worked. Does anyone have any idea what it could be?
