Just upgraded to 40.0 and the minimize, maximize and close buttons are now gone while maximized. When not maximized, I can see the icons but can't click them.

If you use a non standard Windows theme or made other appearance changes then try to revert those changes and use a (different) standard theme or Windows wallpaper.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
