Firefox opens with small window in upper left corner, but full screen.
I have not added nor removed any extensions or add-ons. I simply opened firefox today and the window took up my whole screen as usual, but the actual browser, menu bar, etc only took up the top left corner of that window. The menu bar and all buttons on the browser work, but they act as if they are still in their original place, not where they are on the screen. To explain, it's like if you went to click the close window box on what you see, you'd be about 1/3 across the top of your screen from the left, but it's not there. You then go to hover over where it normally would be, on the top right corner, and then the close window box turns red to close. So it still thinks it's full size, but it's not. I can restart in safe mode and then it works, but as soon as you close and reopen, it goes back to mini Firefox. Attached is the image of what I see. Firefox opens and takes up the whole screen (where you see the small window and then the rest is white background).

I tried the compatibility thing, and went into the "change high DPI settings" and then unchecked the box "High DPI scaling override" and now it works. I don't know if that's what you meant, but somehow something for changed on my PC with a Windows update and the next morning it didn't work. So I will remember this if it ever happens again. Thank you!

The screen shot wouldn't upload with my original post so here it is now.
Check that you do not run Firefox in compatibility mode or with a reduced screen resolution. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
Try to rename/remove xulstore.json and when present delete localstore.rdf in the Firefox profile folder with Firefox closed.
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.
