Thunderbird will not start, seemingly after a Windows Update, and displays the message Error: Plaform version '91.6.0' is not compatible with miniVersion>=91.5.0 maxVersion<=91.5.0

Any replies to [email protected] because I cannot access the email account used for Mozilla

I did not pick up your email, because Thunderbird was not working,

Thanks anyway
