Firefox window won't maximise

The last couple of days, Firefox opens in a three-quarter screen size window. I don't want "full-screen" mode but I do want the window to take up my whole desktop when I'm using it. There are no buttons to maximise or minimise and no dragging arrows when I hover over the edges. I don't know why this is happening all of a sudden. How do I fix it please?

Does it still happen in Troubleshoot Mode?

Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

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