Thunderbird Community Forum

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

“A fake login page at auth.tb.pro appeared while adding an Outlook account in Thunderbird. It is NOT a Thunderbird or Microsoft domain. Do NOT enter your password.”

Is this a known scammer - have others been caught by it.

I hope I avoided trouble by not responding and following the instructions I was able to get from Microsoft CoPilot to locate and remove the the dangerous cookies from my PC.

My screenshot shows the cookies that were there.

Today, I have received an email, claiming to be from Mozilla support.

The text is garbled but it appears to contain words, 'hacking', 'paynalti', and 'auto-block'. These are words which immediately put me on security alert. I haven't opened the mail but have viewed it in preview pane. and screen grabbed the attached pdf image.

Any comments?

Thanks, William

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?

Since I upgraded to 152.0.1, some s/mime encrypted messages do not display. This happens for both old and new messages. Moreover, for these messages, the flag of "new" stays active even after I click on it, suggesting that thunderbird did not "read" the message. The encryption is done by posteo.de automatically for any email that arrives to me. Even the simplest email just written "test" fails systematically when I send it to myself, but some messages sent from others also fail to display. I have installed the extended support version 140.12.1esr (aarch64) to check, and the emails display fine with it.

Anyone with a similar issue or idea of the problem, which I guess might be a bug? Thanks, cassio.

My default email address ([redacted-1]@btinternet.com) has been hacked and access to my contact list gained. Many contacts receiving emails purporting to be from me.. I have changed my default address to another one ([redacted-2]@gmail.com). What do you suggest I do or should I report it to another organisation? Thanks, Peter Russell

i can still see my email folders but these popups appear for each email account in thunderbird (mac osx high sierra) never saw them before so seems something has been compromised? tried to screencap but it's only showing about: url but urls zip by and was able to catch the url a few times earlier but not now.

my accounts are valid this is a new problem just appearing for first time ever

"thunderbird is up to date" for mac os x high sierra

I have just setup Thunderbird and it seems to work fine. when I login it asks me to to enter my password and if I follow the instructions, I am in, fine. But if I just cancel without entering my password 4 times I am in as well. Is there an settings I need to change so I can not open my mail without my password? I am using Windows 11

As per the title. I have allowed external content for one message (it is disabled by default). Finding the option to do that was easy, because there is a specific message with a drop-down menu to configure access to external content for that particular message.

However, now that I have allowed external content, I do not wish to keep it allowed (no need for external parties to know when and where I open and re-open and re-re-open this e-mail). The drop-down menu to manage the privacy options for this particular message has disappeared. That is inconvenient, to say the least, because I can't see any other way to get to those options. What am I missing?

I have 'Allow remote content in messages' turned off.

When viewing a message with remote content, I see the bar "To protect your privacy, Thunderbird has blocked remote content in this message", however the 'Preferences' dropdown described in Remote Content in Messages does not exist...

I want to show remote content for a single message, but this seems impossible!

What am I doing wrong?

Hi Team,

Greetings!

I need your assistance regarding password protection for the Thunderbird email client.

I have configured an IMAP account in Thunderbird and enabled the **Primary Password** feature. However, if I cancel or skip the password prompt during startup, Thunderbird still opens successfully, and all previously synchronized email messages in the Inbox remain accessible. The user is also able to view the mailbox and access email content.

My requirement is that "Thunderbird should not open, display any email messages or allow Send/Receive operations unless the correct password is entered".

Could you please advise if this functionality is supported natively or suggest the recommended approach to achieve this?

Looking forward to your guidance.

Regards, Ps Cheema

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 .
