When I open FF, the window only displays the top menus. If I click the Green dot it will then open full screen. Pressing the green dot once again only displays that 1 inch window. The problem does not occur in safe mode for Firefox. I turned off all of my extensions and turned off hardware Accelerator mode yet the problem still happens.

This just began yesterday and I don't believe I installed anything.

Chosen solution

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed (on Mac: Firefox -> Quit Firefox).

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
