Since Windows 10 upgrade Firefox won't open, I'm able to execute it but the window won't maximize (I can see the small image when hovering over the taskbar). I also remember that Firefox worked shortly after the upgrade for like a month but started to get slower. Also the last times it worked, it started to crash after startup and I had to kill the default startup page.
