Thunderbird 78 won't connect to server working in 68
Hi guys,
I searched in all places I could find, but cannot solve this problem.
I recently format my computer and when installed the thunderbird, it installed the new 78 version. After many attempts I could not download emails from my work. It says it connected, but it can't download anything. I thought it could be me entering the wrong credentials/configurations, but I downloaded a 68 version, and with the same configurations, it worked right away.
One thing I notice, in version 68, it shows a warning for the certificate to accept the risks, because my work email server is self generated (I think), and on 78, this warning never appears. Is there some new functionality on version 78 that stops this possibility? How can I see whats causing the problem, even if that tells me what to do with the certificate.
Thanks in advance. Luís Pereira.

So, I tried what you told in the last post, nothing worked. But I managed to make it work.
What happened was that I found out what the windows that appears on version 68 was, and that was to accept the server certificate wich has a hostname different from the one I was accessing. The hostname in our certificate is for use inside the company network, and from outside, we use another hostname pointing to the same place. This was the windows that do not appear on version 78, and I needed to get the certificate manually and authorize it. This was something that I tried before asking the question here, but forgot to add the port at the end of the hostname, so it did not work at that time.
But thanks for your help, I did manage to learn something about the TB.
As a side question, do you know why this confirmation window do not appear in TB78?

On TB v78 the minimum requirement for SSL has increased and probably your email service provider still uses deprecated security for the mail server and so TB can not even connect to that server (to show you the info about own certificate). Can you try to set lowest security by following the below steps and let us know how it works? From the menu at the top right, go to Options. Scroll all the way to the bottom and click on Config Editor -> Skip past the warning. Scroll down until you find security.tls.version.min (or paste security.tls.version.min to upper frame) Change the value 3 to 1. Restart TB. If it's still not working you may have to change the preference security.tls.version.enable-deprecated to true
Hello svlad2009, and thanks to your quick response.
I tried to do your suggestion, but did not work. Lowered the security.tls.version.min to 1, and enabled security.tls.version.enable-deprecated, but the behavior is the same (I made the changes step by step, not all the same time, and restarted TB each change I made).
Do you have any more suggestion?
Thanks.
Do you get any message with an error? If not then can you add a screenshot with the errors (only - so remove info/other tags) from the error console - ctrl + shift + J (all 3 buttons pressed in the same time)
I get some, but I think they are not related. If I clear the console they don't come up again when I press Get Messages. They only show after startup.
But here they are so you can check them by your own.
I can't see something specific there... You might try though 2 more things: start Thunderbird in safe mode (hold shift when you open the app) and if it's still not working then on incoming server for "connection security" I will change ssl/tsl or startssl to "None".

Your issue may be the same as the one reported here: https://support.mozilla.org/en-US/questions/1306292#answer-1354241

I think I saw the same behavior in some browsers and it was related with "samesite" option. If you have time and wish to try you might change network.cookie.sameSite.laxByDefault from false to true far as I could understand from what that options does...

I will try this suggestion and report back when done
Hello, did you solve the problem ? I have the same kind of issue : since TB78.5, I am unable ton connect in IMAP to our mail server with ssl or starttls activated. I tried the solutions given here in the config editor but it remains the same. Any idea on how to get around this difficulty and have ssl working back again ? Regards
Hello,
I thought I came back here to post the update, I guess I forgot.
None of the solutions helped, what helped was went to the certificates settings and added the certificate to the trusted ones. I'm not on computer now, but you should easily see a page with a url and a "get" button to add the certificate.
I already tried this approach during the questions, but I forgot to put the port in the url, and because of that Thunderbird was not finding the correct certificate.
I will mark this as solved.
Thank you all. Luis Pereira
I miss read, after all the chosen solution is already what I just described, and is a post made by me.
