Thunderbird Support Forum

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?

I've configured an external gpg key for use in Thunderbird, but I'm unable to decrypt an encrypted message sent to myself via thunderbird. I've attached the error thunderbird gives me.

Sending a normal email, a signed email and an encrypted email works just fine. Verifying a signed email also works fine.

Extracting the GPG message, and attempting to manually decrypt it via gpg gives me the following error:

$ gpg --decrypt enc.txt gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01

     "REDACTED"

gpg: encrypted with cv25519 key, ID 0xREDACTED, created 2020-01-01

     "REDACTED"

gpg: [don't know]: invalid packet (ctb=2d) gpg: [don't know]: invalid packet (ctb=2d)

I followed the instructions here to setup my YubiKey OPGP w/ Thunderbird: https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards#Configure_an_email_account_to_use_an_external_GnuPG_key

Now and then, when I press the Enter key, Thunderbird moves the current email message from Inbox to Trash instead of opening the message in a new tab.

I am using Version 115.11.1 (32-bit) on Windows 11.

I would like to delete a mail without opening the mail or without a right-click.

Please refer the images to understand what I am saying.

The attached pic is from Windows default Mail app. I was talking about the red delete icon. Is it available in thunderbird too?

Thank you.

I have various multi-members set up on TB. Most of the time, I use them just as they are, but on occasion, I would like see the members of the list displayed in the "TO" field of the email, so I can delete one or two of them from a specific email. Is there a way to do this?

In Windows Live Mail, for example, clicking on the name of the list would display the members. This doesn't work in TB. Is there a similar function?

Hello, When I try to add my Gmail account into thunderbird, it goes this way : - enter my id and PWD - continue : IMAP and SMTP servers are automatically detected - continue : I am redirected to a google sign in window where my id is already filled. - continue : instead of asking my PWD, Google sends a 400 bad request error.

How can I add my Gmail address?

Thank you. Juliette

The settings menu gives me the option to mark an email as junk and then either move it to the junk folder or delete it. Fair enough.

But once messages are in the junk folder, I am trying to find an easy way to THEN delete them without clicking on "delete selected messages" which then sends them on to the trash file, where they AGAIN need to be deleted.

Assuming there's currently no way to do this, would it be difficult to add "empty folder" option to the junk file? That would save an unnecessary step.

I don't like to delete them straight off because I might accidentally delete a message I want to keep, so I use the junk folder to give them a second chance as it were. But I'm trying to avoid the third chance.

Hello,

I am running Thunderbird 115.12.1 (64-bit). I somehow turned on the number of messages and folder size and can't seem to figure out of to remove them. A colleague suggested I click the 3 dots to the right of the "New Message" but I don't see them at all. Please advise. Thank you!

I am unable to login into Gmail, nor Exchange 365 on Windows with OAuth2.

In the Google auth flow, clicking "Allow" to grant permissions to Thunderbird causes the page to hang and nothing happens.

The default attribution line created by Thunderbird when replying doesn't work well when sending e-mail to Outlook users. [Unfortunately, Outlook users comprise 100% of the people to whom I send emails in TB.] TB's default attribution line causes Outlook OWA to hide the entire reply from the reader unless they click on a [...] button to show it. Then when displayed, the entire message is quoted/indented.

Yes, this is a bug in Outlook. No, it's not going to get fixed.

This can be avoided by changing the attribution line which current defaults to:

       On <date> <time>, <name> wrote:

Simply adding a space after the colon at the end of the line "fixes" the problem, but it's annoying to have to do that manually.

Can that attribution line be configured somewhere?

I've found all sorts of addons that let you muck with the headers of replies, but the headers are fine. It's just the attribution line that needs to be fixed.

TSO Host migrated all my email accounts to a different server. All my emails have stopped downloading to Thunderbird. I cannot find a way to configure my TSO Host email accounts since they upgraded their servers to Cpanel deluxe yesterday and neither can anyone at TSO Host.

I would like to set up an email account with a pen name that I am using as an author. Is there a way to do that without giving my actual credentials? Thanks for your kind attention.

I seem to have lost the search bar that allowed me to find certain emails in specific folders. I am now left with the one that searches all my email folders. Why? How do I get it back?

Thunderbird 115.6.1 (32-bit) on Win 10 and Win 11, local calendar, no email invites are sent to the listed Attendees. Correct email is entered on Calendar/Properties/Email and Notify attendees is ticked on New Event dialogue. Attendees are correctly entered under New Event/Invite Attendees. After clicking Save and Close, there is no Invitation email record in "Sent" emails and the Attendees do not receive email invitations. The event *is* saved in the originator's calendar.

The invites were correctly sent on the Win 10 PC up until TB version 113 (?), when they stopped working after the update (I think). Eventually email and calendar data were transferred to a fresh TB installation on a Win 11 PC, but the invites are still not sent.

The only difference that I can see between this non-email-invite-sending version of TB on a WIn 11 PC and another Win 10 PC where the invites are sent, is that "Troubleshooting Information/Force Email Scheduling" is set to true on the non-working version and is blank on the working one. Clues where to look next?

Hi there I must say having used Thunderbird for probably ten or more years that V115 has been a big pain in the butt to get used to. Why change everything? It was fine before.

OK I can get used to a completely different layout and changed menus even though I don;'t want to but I cannot figure out how to change the background from solid black which I hate. I have spent several days on and off looking for an easy way to do this and can't find it.

So now I go to write an email and the black screen doesn't show anything with black letters of course?? What is the reason for this? So I have to change font over and over to white color.

When I read new emails no problem background is white and font is black like a normal screen. Who had this bright idea?? Please give me a simple solution not involving Css whatever programming such stuff I cannot figure out and don't want to learn. Thanks so much

The latest update of Thunderbird somehow made this message appear "This is an unsupported version of Thunderbird!!" (see attached picture). Is this a bug? I've checked the version on the homepage and it's the same that's running on my PC (Windows 11).

I subscribed to a blog as I usually do in Thunderbird but it ended up as a folder. I've tried to delete it but it doesn't go away. There are no posts in it either and resubscribing to the blog doesn't work - it just says I'm already subscribed. Any suggestions?
