Steps to reproduce:
FireFox 71 0b7 has one serious bug
Tab was opened per window.open() and then inside that tab it entered fullscreen mode per *.requestFullscreen() and somewhen was closed by window.close() (or location.href changed)
Actual results:
By action above after window.close() browser closes the tab but remains in pseudo fullscreen mode. That means entire FireFox remains in disabled control menu mode where you see only original opener page that has initially called window.open but in fullscreen mode. So you need to reenter fullscreen and reexit it to display controls again.
Issue is not occuring if tab is root, also when it has no window.opener
Expected results:
When tab was created as new tab it should leave fullscreen automatically by .close() tab or by changing location.href
like it used to be before.
By circumstances described above Esc button has not more effect after this bug occurred until you reenter fullscreen mode.
Try the Firefox 71 beta 8.
