I have a small number of clients using Thunderbird within Win10 for email, and since it updated automatically last night to Vers 78.5.0 they can no longer download XTRA mail using the usual settings of Port 995/SSL. One of my affected clients using a privately hosted mail server was able to revert to Port 110/No encryption for now, but XTRA doesn't support this. The following is what I found on the Mozilla forum.

“Thunderbird 78 has stopped out of date use of SSLv3 and TLSv1 If server uses out of date insecure protocol then it's not Thunderbirds fault."

"Mozilla disabled TLS 1.0 and 1.1 in the latest versions of Firefox and Thunderbird. Thunderbird 73b and above. This causes issues with anyone connecting via SSL/TLS/StartTLS to services uses 1.1."

I've tried various settings options without success. Outgoing mail is still fine. Any ideas?

Not much help but the service seems to offer TLS 1.2, so probably Spark is not the culprit here:

SSLv2 not offered (OK)
SSLv3 not offered (OK)
TLS 1 offered (deprecated)
TLS 1.1 offered (deprecated)
TLS 1.2 offered (OK)
TLS 1.3 not offered and downgraded to a weaker protocol
NPN/SPDY not offered
ALPN/HTTP2 not offered

Seen heaps of Thunderbird issues today. Not sure what specifically is causing the issue - don't think it's specifically the new update as that's been working fine for a few weeks.

You're not running Eset AV by any chance?

The update changed the auth protocol from some stupid reason. Switch it back to normal password in the account settings. It'll be set to Oauth2.. Ive had a few people ring me about it over the last few days.

Thats a whole other bug for today.. I switched one person back to 68.12.1 today due to his email just not working at all. Works perfect on that. The whole 78.x versions have just been a piece of crap. Over the last couple of days mine (running gsuite) cannot save to drafts, my customer this morning had no emails updating at all and couldnt save any sent items etc. Hence why I switched him back to 68.

Yes, both are running Eset NOD32 or possibly Eset Smart Security.

It does smell of what can happen with AV middle ware hooking

Disable AV (start with email protection) and retry for kicks

google chrome and edge no longer support SSLv3 and TLSv1 since march

and some email client too

most email servers software have been updated

so its the xtra servers that are out of date so blame spark !

I had 70 odd end pcs in the same position yesterday. Expecting more today.

Mail Servers they connect to are fully updated running tls 1.2 and 1.3

Some had Eset but not all.

However does seem to be related to those who have run tb for a long time. As manual removal and full reinstall gets them running again. Pita

The issue's we're seeing seem to be caused by Eset's SSL filtering misbehaving.

Right....think we've got it sorted haha - well the issue caused by Eset anyway.

Open TB, go to options/privacy & security, manage certificates, find Eset's and delete it.

Close TB.

Open Eset, and disable, save, then re-enable the SSL filtering as per these instructions.

Open TB - you can check, but the certificate should be automatically re-created with a current date

Issue should be resolved.

Excellent. That's fixed the 2x XTRA clients I have. I only had to disable and re-enable SSL filtering in Eset to resolve their ones.

That would explain my customer yesterday having issues with g suite since he also uses eset. Switching back to 68 also fixed it. But I have definitely had 3 customers using tb 78.5 who had their authentication changed on the update which I thought was most strange.
