Hi, I am accessing a remote Windows 10 desktop PC using Real VNC, TeamViewer, NoMachine and others.

The point is Firefox and Chrome appear as a white / blank windows when opened, a thing that it doesn't happen to the native Internet browser = Microsoft Internet Explorer and MIcrosoft Edge, that both behave normal. That obliges me to use Microsoft's browsers instead of my loved Firefox.

Could anybody tell me why FF and Chrome are not broadcasted and instead I receive a blank, white window that I can do nothing more than to close it?

Thanks. PS: My client machine is a Windows 8.1 and the remote one with the browsers is a Windows 10's.

Isisombululo esikhethiwe

Hey Fulmercurio, I did some digging around and may have found what was causing it. Apparantly in Windows 8, anything that requires GPU processing would not be rendered (ex: closed laptop lid or no monitor). It's possible that this may have carried over into Windows 10.

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  1. Click the menu button New Fx Menu and select Options on Windows or Preferences on Mac or Linux.
  2. Select the Advanced panel and then the General tab.
  3. Uncheck Use hardware acceleration when available.
  4. Restart Firefox and see if the problems persist.
