I have lost all my Thunderbird data due to the fact that I have a new PC with Win 11 (previously Win 10). I have not safed the mails and adresses on a separate storage device. This question was already answered by David and he asked if the old PC is still at hand. It is, but the harddisc was formatted and is now used in the new PC.

Is there any chance to rescue the lost data? If not it is not a real drama, but a mess! :-)

I have CPTSD to yellow color. It is possible that I will feel headaches or stomachaches after I see that color too often. I just wonder is that possible to let us change the color. It is fine we cannot and I just allow remote content instead.

Issue 1: When using Shift+F5 to Get All New Messages: This command used to go through my accounts within several seconds; but now this can take several minutes. What changed to cause this?

Issue 2: I have one account that is having server problems... causing must click popups in TB. How do I exclude this account when using Shift+F5? I've tried Unchecking the boxes for "Check for new messages at startup" and "Check for new messages every xx minutes". And one help result suggests "Disable immediate notifications: Uncheck"; but I do not see such a setting.

i am trying to copy my Thunderbird to a new laptop. I am asked to enter my password but I did not keep a note of this. How can I find this password to complete getting Thunderbird on my new Laptop. I am 87 tears old and not very technical minded. please make any answers simple. Thank you

Thunderbird is not synchronizing with Mailfence. My other email accounts (Outlook, Gmail) work fine. TB connects to them, downloads message headers and displays the number of messages correctly. With Mailfence, the messages stop at "connected to imap.mailfence.com" and stalls there. The message disappears after a few seconds and nothing else happens. This happened this morning when I first launched TB. I then got an update to 128.11.1. No change. I did receive the Windows Update 2025-06 Cumulative Update sometime overnight prior to launching TB.

Somehow I have lost my check and download email buttons at the top left of Thunderbird. I have checked what I believe is every option to get them back but to no avail. Somehow I hid the easy enough but now they are gone I can't seem to find out how to get them back.

Thoughts? Darren

I sometimes get a message when I'm trying to send an email that says

Sending of the message failed. An error occurred while sending mail. The mail server responded: (VO-102) Message blocked due to spam content in the message. Please check the message and try again.

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

It does not appear in the message search. Perhaps the emails of a particular account are not included in the search, but is there a way to address this? I have already rebuilt the “global search database”.

All of my read messages have disappeared from Thunderbird and appear to have been deleted. How do I get them back?? I have no idea how this happened as I haven't changed any settings prior to this happening. I just opened my account this morning and they were gone.

I am experiencing strange behaviour with Thunderbird and certain add-ons. For some time now, when I use certain add-ons that are supposed to display a menu, the menu does not appear. It is replaced by a circle (see attached image : two different add-ons, not showing simultaneously, but merged into the same capture). I have disabled all other add-ons, but this has not resolved the issue. I think there must be a setting that is causing the problem. But with so many settings, I don't know where to look.

Does anyone know how to find the reason for this behaviour?

I am using Thunderbird 139.0.2 (64-bit) with Windows 11.

Thank you for helping.

I exported Outlook Contacts to a .csv file and imported giberish to the Thunderbird Personal Address book. Can the giberish be block deleted? How should the Outlook Contacts be transferred to Thunderbird? Secondly, I exported Outlook Contacts to gmail and have used them on the web based gmail app to send messages. Don't remeber how the gmail contacts got to the Thunderbird Address book, but they don't work. The first message I sent from Thunderbird from my wife's gmail address to my hotmail address produced the following error:

Sending of the message failed. An error occurred while sending mail. The mail server responded: The recipient address <Steve Thompson (sthompson2486@hotmail.com> is not a valid RFC 5321 address. For more information, go to

https://support.google.com/a/answer/3221692 and review RFC 5321

specifications. 00721157ae682-70ca8508772sm13401897b3.82 - gsmtp. Please check the message recipient ""Steve Thompson (sthompson2486"@hotmail.com" and try again.

Both imported address books are unuseable. Please help.

I have a laptop with windows 10 & Thunderbird 128.9.1 and a Samsung S10 using the Samsung email. Both are configured with IMAP. When I open the Samsung email to view and download emails, I can then get home and open my laptop with Thunderbird where it will also download.

If I were to log onto the Gmail through a web browser the email will show in the "all mail" label and no longer be in the inbox, unless I do the phone first and it stays in the inbox until downloaded on the laptop.

so I can't get it on the phone if the laptop is used first. Any ideas ? because logging on to Gmail through the web browser to forward it myself is a pain thanks in advance Mick
