User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20151029151421 Steps to reproduce: * Open Firefox. * Press fullscreen button. * Press Alt-F4 to exit. * Re-open Firefox. This is on Windows 10 both on an HP laptop and an Asus Transformerbook. Actual results: * Firefox opens as if in full screen mode, but fullscreen is not activated. * Address bar is not selected. * "Restore Previous Session" is unavailable. * Subsequent activation of fullscreen by use of fullscreen button only changes window state from maximised to windowed. * In order to restore normal condition, the fullscreen button must be pressed, followed by exiting and restarting the program. Expected results: * Firefox should either open in the same fullscreen as before, or open up normally.
