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 .

I keep getting message "The certificate for imap.gmail does not come from a trusted source". I've uninstalled thunderbird on occasion and it fixed this problem, but now it keeps coming back. bold text

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 remote content blocked as a default. If I choose to view remote content **for an individual message**, there seems to be no way to reblock it, because the yellow bar with "options" disappears after you allow the remote content for that message. (Whoopsy! Changed my mind! Let's say I don't want the remote content to transmit that I opened the message a second time when I do so.)

Mail Content > Exceptions does not help in this case, since I allowed the remote content from a specific message, rather than allowing a wider permission, such as allowing remote content from a particular email address or website. Copying the message link into Mail Content > Exceptions (as suggested in an old post) doesn't work, either.

So it seems I am now stuck having remote content active each time I need to open that message?

Windows 11 Thunderbird = current at the time of this writing. (150.0.2 64bit)

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.

Hi! I wonder how Thunderbird for Android works regarding security and privacy? If I use a Gmail account via Thunderbird, will I not miss the security features that Google provide, like warning for malicious/fraudulent emails? How can Thunderbird improve my privacy? I mean, Google will scan my emails when they are coming into or leaving the server anyways, I guess. And they will still let AI be trained on emails resting at the Gmail servers, so will there be any privacy benefits using Thunderbird? Please help me understand, because I have really liked Thunderbird for Windows and used it for many, many years when I had a Windows laptop as my main computer!

Hello, I use Thunderbird 140.10.0esr, installed as Flathub flatpak on Fedora Linux Kinoite. I just found out I have a folder in /home/<user>/.var/app/org.mozilla.Thunderbird/.thunderbird/1tniiwpw.default-release-1/storage/default/ called https+++www.googletagmanager.com. I wonder why I have this and what it does in the Thunderbird settings. It has something to do with Google's LLC, but I don't want to be part of that. I removed the folder completely and hope it won't come back, but I wonder. Who can tell me something more about this folder? Thanks.

Hello! No real issues or bugs to report, but I had some curiosities about independent audit documents. I appreciate the dedication to privacy and transparency, as I am sure many do; I've noticed that there are readily available audit documents for the Thunderbird Send and K-9 which is cool - are there any such audit documents for Thunderbird Desktop for Linux, or do the aforementioned documents sort of cover the same thing? If you could help me understand this (or perhaps point me to information or docs I missed), that would be appreciated!

Thanks for your time, --Mark

I have always used the default option to block remote content in emails, and I always see the yellow box. However, I happen to have admin access to a server that sends me certain emails, and it has logged when I opened emails from there.

Is it possible to somehow incorporate a virus/trojan checker into the software that is open source for Windows? I keep getting TONS of alerts from Mcafee that it caught viruses. Also wondering if this could be a addition to Thunderbird in a new release by incorporating something like CLAMAV into thunderbird software somehow?
