Firefox has lost its window frame, looks like a super zoomed in window without any bars
My Firefox has lost all its application frame, and toolbars. It basically looks like an extremely zoomed in borderless window, and whenever I zoom in or out, everything is locked into the top right corner. Nothing is displayed properly. I reinstalled it, and that did not change. I looked at my Macintosh accessibility settings, nothing is changed there. Please look at the screenshot.

I erased the entire Firefox applications support folder. Then using Activity Monitor, force quit Firefox. Then restarted the computer. That solved it.

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.
- Help -> Troubleshooting Information -> Profile Directory:
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
That did not fix it at all. I will try completely removing all the Firefox stuff and reinstalling. Thanks.
Did you try to reset the zoom on this page?
You may have accidentally zoomed web page(s). Reset the page zoom on pages that cause problems.
