I installed FireFox 43… and everything was working fine. Then, even though the browser was started (mouse over showed the open page’s thumbnail image), the window itself would not maximize.
I went to the ridiculous extreme of uninstalling and reinstalling FireFox (using Revo – so I’m pretty sure that the uninstall cleaned up after itself) and I am still having the same issue – that is the browser starts but the window doesn’t maximize. The browser doesn’t shut down with the Close Window choice off the right click so I have to use Task Manager to shut it down.
I didn’t love using Internet Explorer in earlier versions of Windows and I don’t especially like Edge either. Firefox has been my browser choice for as long as it’s been available and I still want to continue using it.
Any notion on why the window won’t maximize and and/or how to fix it (without re-installing Windows or creating a new user account and starting all of the customization over again)?
