I was issued a new certificate in January, 08th, 2025, and Thunderbird seems to not recognize it as being valid. I´ve double checked all CA´s chain, they are all installed in the computer. When I examine my personnal certificate, the only difference from other certificate that I have installed in the same machine (that is readly accepted and recognized by Thunderbird) is that I see this information in the first level (sorry, in Portuguese-BR):

Restrições básicas Autoridade certificadora Não

I understand this may be some additional information that is present in the certificate, and that is leading Thunderbird to believe my certificate is not valid, as the certificate itself posts that it´s not a CA. Of course it would not be, it was issued by a chain of CA, that is completely valid. Any thoughts?

I get Microsoft authenticator on Thunderbird windows needed ... 14 days left (Microsoft 365 email address)

All worked fine until a few days ago.. getting it on two email accounts.

Clicking on install MS Authenticator, it only shows instructions to add that app on a phone....

Somehow my email is being distributed to all kinds of spam operations and I get at least one new Junk sender every day. I have tried hitting the Junk button for all such emails. I have tried filtering the senders off to Junk, with variations--eg, even after marking as Junk email from "enzo@newsletter.spartoo.com" I set up a filter so all "spartoo.com" goes off to Junk. And I edited the filters to make sure they weren't conflicting with each other. But nothing works and I feel like I'm in Junk Hell without any support from Thunderbird. Halp!
