Thunderbird ஆதரவு மன்றம்

I updated my comcast password recently. Now when I try to send an email I get error about password - dialog comes up one option being reset password. When I click this I expect a dialog to open allowing me to enter the correct password but nothing happens.

I went to saved password dialog and removed the entries there hoping that would force Thunderbird to ask me for password - no joy.

In the Beta version how do I update SMTP password? I do not want to recreate the profile because then I lose lots of stuff - I JUST want to update the SMTP password. None of the pages I find are helping me.
