When I open Firefox on a MacBook Pro the screen opens in a small window. How do I get Firefox to open normally?

You can try to rename/remove xulstore.json 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.

The Firefox profile folder is in a hidden location in the Library folder in your user directory (~/Library is a hidden folder).
