Yesterday, Oct 6, at 3:20 pm, tbird was unable to download messages from my att server. The error message is "The certificate for inbound.att.net does not come from a trusted source". Nothing that I know of has changed when I look at the account settings.

Do I need to contact Att/Yahoo? If so, how can I describe what to tell them, as I have no knowledge of certificates and how they work (or don't work).

Bonjour,

Il semblerait que mon compte Thunderbird soit piraté. Tous les messages que je reçois sont précédés de la mention "[hotmailerrr_bot] Security Alert: " En dessous apparait un écran noir sur lequel est écrit: "This mail was moved to your cloud lounge" suivi d'un texte faisant la promotion d'un "Premium Cloud". Le message original ne peut pas être lu et si il y a une pièce jointe, elle est éliminée.

Ce problème est-il connu ? Y a-t-il une solution ?

Remerciements

Explain the problem I have already described!! - When I try to read an e-mail a 'box' appears saying 'Thunderbird: The certificate for imap.shaw.ca does not come from a trusted source'--What is this for?? _ Yesterday an e-mail I sent to several contacts showed as 'Sent' BUT did not register in my 'Sent' folder ----I had to phone England to check that they had received the e-mail, which they had. Today I was able to send e-mails & they were recorded in my 'sent' folder BUT the other problem still persists. Please advise if there is something that can be done to correct this problem. Thank you Phyllis M.

I have a trojan in one of my emails. Every time I start TB McAfee catches the bug. I cannot find it. What processes does TB execute while loading. I want to be able to isolate the the bug. What tools can I use in TB to help with this.

As an 80 year old woman of sound mind and competent in most things I still struggle with AI & IT! Can anyone advise or help me restore my system with or without my original email? Do I have to change it, change my provider or start again with everything changed? Thank you for any help.

Hi, Will there ever be a functioning option to set up a primary password that aborts the start up if not provided with the correct password. Still in 2026, hitting cancel gives access to all already synced emails. Please, soon!

Recently purchased a new HP laptop. And installed my ZoneAlarm without issue. Then downloaded Thunderbird and installed it. On opening ZA went berserk constantly alerting every few seconds saying there was a Bot. See attached screenshot from the last instance of this. Deleted Thunderbird and the problem disappeared. Was the problem actually caused by Thunderbird and have you any idea what was trying to access the website in the screenshot and what the website is that it was trying to access?

Sometime ago, when I was regularly using more than one computer, I thought I'd found a way to have my Thunderbird address book centrally located and accessible from both computers. I got no success from attempting this, but have suffered some side-effects every since. Configuring Thunderbird back then somehow involved using the location "demo.sogo.nu" and I believe it related to a security certificate. What used to happen was, soon after rebooting the computer, I'd get a couple of pop-up messages about connecting to demo.sogo.nu that I could clear away easily. Recently, something changed regarding this certificate and I now get pop-ups (screenshot attached) that continually bother me to create a security exception. I want these gone! I've gone into the Certificate Manager and can't find anything under the Server tab to delete. One other clue is a second screenshot that I discovered somewhere in Thunderbird that actually shows the *.sogo.nu certificate - but offers no way to delete it! Can anyone give me a hand? My only alternative is to literally annihilate Thunderbird and start from scratch, but I really don't want to go there.

I've just recently (over the past 10 days) been notified about 3-4 times a day by Windows Defender which flagged "something" as Trojan:HTML/ScrInject.AW!MTB in "file" %temp%/newmsg.

That's where my copy of Tbird puts temp files. Closing it stops this behavior. Uninstalling and reinstalling w/out deleting my profile caused the same behavior, but uninstalling and cleaning out my profile files seems to have stopped this behavior.

I only have one extension, Compact Headers, and that doesn't seem to be the problem. Has anyone else experienced anything like this?

The certificate for pop.3marysvilleprint.com is not vailid for that server. Someone could be trying to impersonate the server and you should not continue

Hi using 153esr and Win11

I have my emails on an encrypted drive. Until now if I closed Thunderbird I would have to enter my Master/Primary password before and emails would show, i.e they were protected from casual view.

Now if I type [cancel] at the request for a password, twice in a row than all my emails are visible.

I though it may be this new thing where the [close] icon functions differently, but even if I close via the menu File > Exit it seems Thunderbird still has access to my emails without authorisation.

Any ideas would be useful

Thanks

very recently perhaps with a McAfee or Thunderbird update , I am seeing a message that McAfee stops a threat every time thunderbird does a message retrieval. see attachments. I have checked my outlook account directly and deleted a bunch of messages but it persists.

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

I have a suspicion someone is reading my e-mails. I am using Virgin Media as my ISP and have changed the password on my account.

Is that enough to stop my e-mails being read by someone other than me or what can I do to protect my inbox, please?

I have Thunderbird installed for lots of users on windows 11. Recent updates caused Thunderbird to ask again to set as default, as is normal. However, if you ask it to set as default it brings up a UAC dialog. However, I have installed as a user, and am asking to change a user setting. UAC is inappropriate for the situation.

If I ask Thunderbird to uninstall is again pops up a UAC dialog even though it is not necessary and inappropriate.

Why is Thunderbird asking for more permissions?

I installed as the current user with default installer settings.

When I use thunderbird to download messages from my sky email, I get a threat notice and " The file containing the threat was at c:\users\appdata\local\temp\newmsg" - I use mcafee. I do not get this threat notice when getting messages from my bt emails or my zen emails via thunderbird. I do not get this threat message when logging in directly to sky emails on the internet. I have deleted my sky email account in thunderbird and reinstalled the account but I still get the threat notice. Can you help .
