Firefox browser goes black. This happens on youtube a lot but can happen on any website. Only way to fix is to close and reload browser. This is happening several times everyday and is becoming unusable. This does not happen with any other browser (Edge, IE or Chrome). Been having this problem since using Windows 10 two months ago. Windows 10 64 Bit Firefox 53.03 Flash and all addins up to date. All drivers up to date. No virus or malware.
