Suppose I see 10 incoming emails on my server (core.com). In thunderbird, when I click to download them, I see a message saying something like "downlaoding 10 emails". After that only 2 or 3 of them have been downloaded, the rest deleted. Help! This started happening a couple of weeks ago. I have tried downloading and re-installing Thunderbird, to no avail. Should I change my account settings?

Some months ago I received an email, but the body of the email was a picture (jpg) from my computer. The sender definitely does not have the image. The content from the sender is missing, and my image is in the body of the email and as an attachment.
This has happened a handful of times over the past 6-9 months, with the same image showing up in emails from various unrelated senders.
I just received an email from my partner who sent me an email with a screenshot attached, but instead of receiving what he sent, I've got an email with my image that randomly shows up in my inbox.
A few days ago it happened, but when I restarted my computer, the unwanted image was no longer present, and the actual email content was visible.
Restarting my computer has not resolved this particular instance.
Does anyone know why Thunderbird is in love with this one image of mine and why it keeps showing up in my inbox in emails from other people?
Thunderbird is not responsive when I click on it to open my email.

I am experiencing persistent issues configuring a custom-domain email account in Mozilla Thunderbird, while the same account works correctly in Outlook and in webmail.
Environment:
Email client: Mozilla Thunderbird (latest version)
OS: Windows
Mail hosting: Antagonist / DirectAdmin (shared hosting)
Domain: s23k.com
Email address: jean-paul.sablerolle@s23k.com
Incoming mail (POP):
Server: mail.s23k.com
Port: 995
Security: SSL/TLS
Authentication: normal password POP connection works without errors.
Outgoing mail (SMTP):
Server: mail.s23k.com
Ports tested: 465 (SSL/TLS), 587 (STARTTLS)
Thunderbird fails to send mail with the error:
“The requested domain name does not match the server’s certificate.”
Even after explicitly adding and permanently accepting the certificate exception, Thunderbird continues to reject the connection.
Important observations:
Webmail (Roundcube) can send mail successfully.
Microsoft Outlook can send mail successfully using the same SMTP server.
Thunderbird never completes SMTP authentication because the TLS handshake fails on hostname validation.
The certificate presented by the server appears to be issued for a different hostname than mail.s23k.com.
As a workaround, I am currently using an external SMTP server (KPN: smtp.kpnmail.nl), which works correctly in Thunderbird.
Question: Is Thunderbird intentionally stricter than Outlook regarding TLS hostname validation for SMTP, and is there any supported way to:
properly override this hostname mismatch for SMTP, or
diagnose whether this behavior is expected and unavoidable with misconfigured server certificates?
I would like to confirm whether this is expected Thunderbird behavior or if there is a configuration option I may have missed.
I am not trying to weaken security; I want to understand whether Thunderbird allows any safe override in this scenario or if the server configuration is fundamentally incompatible.

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.

I am trying to download Thunderbird on my PC. I donated to Mozilla yesterday. When I try to install it asks for another donation.

I have a new Brother printer MFC-L3780CDW. I can print from Foxfire internet, I can print from Microsoft Word. I can go to my Comcast online account and print emails, but I cannot print an email from Thunderbird from my desk top. I right click the email to bring up the menu. I select print and nothing happens. It dont bring up a print preview window to select printer. It does nothing. My old printer was also a Brother MFC, just an older model. everything worked fine. I called brother and they say since everything else prints it must be a problem in the Thunderbird Application

I am unable to send tabs from my desktop devices to Firefox on my Android device.
- All devices are logged into Firefox Sync. - Sending tabs from Android to desktop works fine. - Attempting to send a tab from desktop to Android, nothing happens. Have tried with multiple different tabs from multiple desktop devices, it never makes it to my Android device. - Synced tabs works fine. I can see the open tabs on all my devices from all my other devices, and it stays up to date. - Have tried logging out of sync and logging back in. Didn't fix the issue.
Desktop devices are running Firefox v146.0.1 on Windows Android device is running v146.0.1 on Android 16 (Pixel 8 Pro)
What do I have to do to send emails out? When I click on "send" then the emails are stored in the outbox but haven't been send.
Thanks

After having created a couple of tab groups with some of the numerous tabs that were already open in my browser (Firefox, of course) and then closing and reopening the browser shortly after, no tabs at all reopened even though this is my normal setting for Firefox: open all previous tabs when opening firefox. This setting had always worked before - as it does now with the new tabs. However, all my previous tabs as well as the freshly created groups have vanished. Do you have an explanation and ideally a way of recovering the tabs - or the groups at least? Thank you very much. Kind regards, Kerstin
