This is a dire unapproved forced update effect... can I revert back to the correctly working previous version? Or have all services authentication servers been hacked or attacked and disrupted and it's not the Thunderbird recent update at fault? It would be more useful on these windows notifications of authentication failure if it included the email address that was being logged in or attempted to be logged in was displayed in the windows notification of authentication failure rather than just the domain name of the server which could be the same for multiple accounts so we cannot diagnose which account is either having problems or being blocked due to some bad actor attacking the account.</P> Mon, 31 Aug 2026 18:55:46 GMT UK_TK1 2026-08-31T18:55:46Z https://connect.mozilla.org/t5/discussions/all-account-authentication-errors-on-thunderbird-update-to-153-1/m-p/136543#M55158 <P>Hi two accounts on yahoo keep throwing up re-authenticate windows... gmail and hotmail.com addresses keep throwing up intermittent authentication error notifications via windows notifications but no authenticate windows.
