I wish to add a new PC to devices I am currently syncing (a "legacy" PC, a laptop, my iPhone). I can confirm from the legacy my correct password and can log in using it. I have installed the up-to-date Firefox on the new PC. When I attempt to log in to Firefox/sync on the new machine, it will not recognize the confirmed password. FYI, this is a new password created Aug 23. The new machine runs Win 11, the old Win 10.
