how to turn off mozilla thunderbird update

Is there some way to stop that dialog from popping up? I would really like to stop it harassing me to upgrade - I will upgrade when it is okay for me to do so. I don't want that to happen again - I cannot currently run on 78. I didn't find out about it until I rebooted my machine and reopened Thunderbird. I am afraid that at some point that dialog box popped up, stole my focus just as I was hitting 'RETURN' and it downloaded and installed 78 in the background. Something like once a day, Thunderbird pops up a dialog box asking me if I want to upgrade and it appears that the affirmative is the default selection. I think I may know, now, how the second migration to 78 happened. Once again, I went through the painful backward migration but kept wondering how the second forward migration happened since I had turned off automatic updates.

Then, out of nowhere, when I rebooted my machine I was back on 78 and have no idea how that happened. It wasn't easy but eventually I got myself back to version 68 and turned off automatic updates to be sure that I would stay on 68.

In the middle of all this, Avast, apparently independently, produced prompts to install updates and to reboot.A while back I upgraded to version 78 only to realize that was a major mistake for me. I then followed DavidR's advice and exported and imported the Avast Email Certificate, to which Thunderbird responded 'Alert: This certificate is already installed as a certificate authority', after which Get New Messages for GMail still reported 'Thunderbird: Connection to server was reset'.

I end up in an infinite loop, where I enter an email address and click a blue 'Next' button and am invited to try another 'Email or phone', or enter my only phone number in various formats and am told 'Couldn't find your Google Account. (with Mail Shield off) Get New Messages for GMail prompts me to 'Enter credentials for on ' and 'Sign in with you Google Account', at which point it is not at all clear to me which of several linked email addresses is expected. (with Mail Shield on) Get New Messages for GMail still reported 'Thunderbird: Connection to server was reset'.Ģ. I first followed alanb's advice and changed authentication method to OAuth2 in both incoming and outgoing (SMTP) servers, after which:ġ.
