My tool bar has completely disappeared, and pressing F10 or ALT or the two together doesn't matter.

Also, sideways on the page margins became broader - do not know if the two are related.

Could you make sure that Firefox is not in his view "full screen"? On Windows, you should be able to exit the full screen using either:

  • F11 key (this screen full switches on and outside)
  • Drag the pointer of the mouse to the top of the screen, try a few points if necessary and the toolbar area must roll down, then either:

    • Click on the "3-bar" menu button and full screen
    • Right click > exit full screen

Does it work?
