When I open Firefox, it's just a white window with no content. It used to work fine, but when I opened http://www.kotikokki.net/rekisteroidy/ the browser kind of crashed to a white screen. I have tried restarting it a few times, but it's still a white screen. When I hover over the icon of Firefox, it shows my start page but the window is still empty. Heck, even the Windows' close window button is missing. OS: Windows 10 Firefox version: The newest one, tried reinstalling 15 minutes ago. Image of the issue: http://i.imgur.com/5qJ7sMw.png
