some time ago thunderbird was operating normally. i since updated the antivirus software to a newer edition of ksos. after that, when loading i got the confirm security exception and my pop3 account was operating normally. after a week or so, i pressed the get icon two three times in order for the exception to appear. now, thunderbird starts and i dont get the notification at all, let alone save it permanently. the only way now to download email, is to exit kaspersky, not even pause protection, for the app, to download email without any notifications. if i restart antivirus, i get the connected to mail.com etc but it gets stuck there. also tried switching ports and no change... ideas?

Regarding certificate:

hey, this kinda helped out but in the opposite way... i found a different way around this. the account is a pop3 using ssl/tls in and out. so, i tried your solution, but i didn't work. so it got me thinking, what if this was a certificate issue all along and not kaspersky scanning and blocking encrypted connections. so, what i did is to force thunderbird to use new certificates from my mail.went into settings, found and deleted all mail certificates. found, 4 surprisingly even some expired, and deleted them all. this seems to works so far....

It seems like Thunderbird version 78 removed the "add certificate exception" dialog altogether, so you now need to add the certificate of the CA yourself. I don't think that's a convenient modification for the user. The "add certificate exception" dialog was a lot more direct, didn't require you to navigate into the configuration, and was easy to use for everyone. Now, if you don't have the correct certificate installed, it will simply throw some error window, or just keep trying to download mails forever, without success.

Please post an update after receiving 78.3.2 (not yet shipped).

I know improvements in this area should be happening, but I am not sure as to when it will happen.
