White Screen Problem In Linux
In linux (ubuntu) I have some serious issue when I open firefox the tabs are going to white and I don't see any buttons and website. But When I Hovering the firefox in mini window i can see browser but in full screen there is only white screen as you can see in image I attached.
What version of Firefox? KDE or Gnome? Have you tried Safe Mode? Firefox safe mode: Click the menu button, click Help and select Restart with Add-ons Disabled…. Firefox will start up with the Firefox Safe Mode dialog.
Try downloading a separate copy of Firefox and run it from the folder(do not sign into you Firefox account) to see what happens.
