FF not opening

When I attempt to open FF V101 it will only open to the left. It will go ahead and fully open if I click on the expand tool in the upper right corner of browser (or what there is of it). Any ideas out there?

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).
