Start by reproducing the failure in MetaMask 13.20.1 on Firefox 149.0 (aarch64) on macOS, using the extension icon and the screenshot as the observed result. Investigate why the extension does not open accounts; done means MetaMask starts normally and displays the user's accounts without repeating the error.
