I Have several synced devices where I can logon to Firefox/Mozilla using the same details, except this machine. It says my password is wrong and checking my password in my account, it has an old password and I can't change it to the current password. Can anyone help?

On a latptop / desktop device where Sync is connected and does now work ...

In Saved Logins Look at https://accounts/firefox.com, instead, then click on Show Passwords. That will show you the user set password. like 8 to 20 or so characters in length

That chrome://FirefoxAccounts(Firefox Accounts credentials) URI will show the 3 "keys" and the 'hash' password all in one continuous string which has hundreds of characters - impossible to manually enter without errors; and I doubt if the password field to a login to Sync will accept than many characters. That is an internal security feature of Firefox installations which are set up to use for communicating directly with the Sync server.
