The ability to select "Done" for New Contacts is totally off-screen on the right when using part-screen (screenshot2 below). When in full screen only a part of the box is available to complete and entry (screenshot1 below).

I've tried adjusting font size and other stuff in Windows 10, but nothing changed the way the Thunderbird looks in this regard.

I'm trying to install Thunderbird on a Macbook - macOS Tahoe 26.2 I've made a donation but Thunderbird won't download.

I did not get any error messages, in fact nothing happened.

Is it possible to copy just the Mail folder from a Thunderbird Profile backup in Time Machine on Mac? I have deleted an email account from Thunderbird and I did not tick Delete Data so the emails are still there in my Profile but they no longer show up in the tree in Thunderbird on my Mac ( OS 14.8 Sonoma). I had a lot of subfolders into which I had put incoming and sent emails on particular topics. For example I had a folder called Family, and inside that I had a subfolder called Birthdays as well as many other family related topics. My last Time Machine back up is about a month ago but that would be good enough to restore from. I tried ‘Import’ in Thunderbird but it only imported the main folders and the emails within but not the subfolders. I have another email address besides the deleted one and if I overwrite the whole Profile with the older one from Time Machine it will lose a lot of new stuff accumulated since that backup. Any help most appreciated

A while back I noticed that an email that would normally have appeared in my Inbox was not in one of the local folders I created. I have a number of message filters that send emails into local folders, but I had not created one for the domain this email came from. Since then, this has happened with a number of emails, in some cases emails from new senders. Also, I'm pretty sure that a few emails that should have gone into one specific folder based on a message filter I created ended up in another.

Any idea why this is happening and how I can fix it?

Under my main email account in Thunderbird there are two Spam folders. I don't know how a second one was created but I'd like to delete it. When I right-click each Spam folder, only one has a Delete option, but when I select it, the Spam folder doesn't get deleted. How can I delete the extra Spam folder? thanks.

I'm having problems getting my signature to appear in Thunderbird as it does in my soon-to-be former email client. I've attached pics of the signature as it should appear and as it appears when imported to Thunderbird. I can edit the HTML code, but I'm not sure how to correct things like the image not importing when the link is correct and how to get rid of the dotted line border that shows up in Thunderbird when it does not appear in my current email client signature. I attempted to attach my HTML file, but cannot. I can post the code, if that would be beneficial. HELP!

The messages do not show in the email folders. it happened after I tried to delete some folders I didn't need. The folders have an icon next to them that lists the number of messages in the folder. When opened, most of the folders say "No message found."

I am trying to set up the latest version on Thunderbird on my wife's old Gateway (WIN 7 home premium). The previous version of TB has problems so I deleted it and am starting over. I have manually configured this TB with the server info from the TB accounts on our other computers, but get the error as stated above. What do I need to check?

I recently had to change my password for my att.net email account. My iPhone and the att web mail have successfully read up to 0936, while thunderbird has only read up to 0922, and I cannot get the new password entered successfully to read any further.

Meanwhile, the sending function also cannot get the new password entered successfully.

This is the same password that now works on web mail and on my iPhone.

Account settings, server settings show the IMAP mail server is "imap.mail.att.net" port 993, username = email address in att.net domain, security is SSL/TLS normal password, Outgoing server default is "smtp.mail.att.net" port 465, same username, SSL/TLS normal password.

Settings, privacy and security, saved passwords locked up the mouse with giant cursor showing, had to close thunderbird via Alt+F4, mouse still locked up with giant cursor, had to close all other windows with Alt+F4, hoping to be able to close this one before rebooting computer.

My name is Yoshinobu OKUMOTO. I live in Nara prefecture in Japan. I use Thunderbird as my e-mail software. My e-mail address is "<edited>@asahi.email.ne.jp". I have received a mail at January 29 18:35, 2026 . In the space for name of a sender of the mail, "<edited>@asahi.email.ne.jp" is written. This is my e-mail address in Thunderbird. I did not sent a mail at January 29 18:35, 2026 . I wonder who sent this mail to me.

When this mail was sent to me, a red spam mail mark was attached to this mail. Usually, when I received a spam mail, I transfer the spam mail to a spam mail folder. But in this case, if I transfer this mail to a spam mail folder, I worries that transformation might transfer a mail from my acquaintance to the spam mail folder from that time on.

In the main body of the mail which I received at January 29 18:35, 2026, it was written as follows.

" Account is invalid.

When this page is displayed, the total of the account "asahi.email.ne.jp" is invalid.

The procedure to confirm the reason 1. Log-in with a browser, for example Chrome, to the account "asahi.email.ne.jp." 2.If the account is invalid, the explanation is displayed."

In the sentences mentioned above, " Account is invalid. When this page is displayed, the total of the account "asahi.email.ne.jp" is invalid." But I can use my Thunderbird as usual except this mail.

Next, I tried to log-in to the account "asahi.email.ne.jp" with a browser Chrome, I could not log-in.

I already received this mail which have the same text three times until now, 1/20 19:17, 1/21 17:21, 1/24 21:04.

If it is necessary for me to forward to you the mail which I received at January 29 18:35, 2026, I send the mail if you inform me of your mail address.

I will be thankful, if you give me some advices in this case.

So, from time to time I need to find a sent email, it is not in my sent folder, I check my settings and there it is, I then set it to use my sent folder on the IMAP server, this works for a while, but then seems the next time I want to find something in the sent folder it has reverted back. Any Thoughts?

I've been trying to add yahoo account for several weeks, I type in the email address on the add account function and then I just get a wheel of death and have to force shut the programme, I'm on windows 11.

When using Thunderbird 140 I am able to setup the background color of the message pane for individual messages. However when the messages are threaded, the message pane shows a preview of all of the threaded messages together in the message pane with a different background color than individual messages.

I need help to log into Thunderbird. I get the same message over and over again (login to server imap.videotron.ca with username...............failed. I've tried several tried and true passwords from before and none fit.
