Reproduce the issue using the stated steps with MetaMask 13.42.0.0 on Firefox and Windows, then inspect the available extension behavior around passphrase entry; the report names no files, tests, or error output. Done means the wallet completes loading after the passphrase is entered in the reported environment and the recurring failure is covered by a verified regression check.
