Can you open its system menu via Alt+Space and resize the window via that menu ?
You can try to go to full screen via F12 to have at least a browser window. You can 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).
