Firefox doesn't open in fullscreen

Usually after I close Firefox while in full screen and reopen it, it opens in full screen. But now for some reason it doesn't. Deleting "xulstore.json" doesn't help.

Works like that for me now, too. Looks like a change in Firefox 47.0.

Further information: Firefox 47 has 8 Bug fixes that are related to fulllscreen. Two are related to e10s and 6 for changes made to the fullscreen API. Not sure which one broke the "restore" previous session after exit in fullscreen mode feature.
