With Firefox 98.0 and macOS 10.15.7, Firefox window fills entire display screen and does not show edges to be able to drag in window size. Is there a way to reduce the displayed window to be smaller than the screen size? Thank you!

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).
