Thunderbird Community Forum

Recently my email subfolders stopped being visible on my Thunderbird desktop. They are still visible and accessible on my Thuderbird Android app on my phone. Any suggested remedies I see call for steps that I don't seem to have in my settings. My desktop SW version shows as 148.0.1 (up to date)

I encountered the following problem while using Thunderbird 140.8.1esr (64-bit): While moving an email from the "Inbox" folder to an archived folder named "2026", I noticed that the archived folder had disappeared! All my searches for a solution have been unsuccessful. Do you have any suggestions? Sincerely.

Program is freezing after a few minutes, even without using, Tried repairing all the folders and everything I could find on google, installed on another laptop, But still the same.

Bonjour, Les mails n'arrivent plus automatiquement dans ma boite mils et quand ils arrivent ils ne s'ouvrent pas (ou alors 2 jours après...). Message : le certificat pour imap.gmail.com.993 ne provient pas d'une source sûre ! La fenêtre "Ajout d'une exception de sécurité" s'ouvre et rien ne fonctionne si je clique sur "obtenir le certificat" ou "confirmer l'exception de sécurité"....J'ai tout testé sur cette fenêtre... Je ne suis pas du tout informaticien... Pouvez-vous m'aider rapidement ? Merci. TAMINIAU Yvan yvan.taminiau@gmail.com

I've developed a thunderbird add on. Now I need an extension ID I've read https://extensionworkshop.com/documentation/develop/extensions-and-the-add-on-id/

So how do I get an extension ID?

Good day support team, I had this sending message error show on my Thunderbird desktop when I try to send Annual Report to my members. I had tested to send through Bcc to 50 recipients and not sure how many is going through or not even one is going through. This is due to the over limit of the recipients I send through Bcc or recipient "bcl5157@gmail.com" account as show on the attached screenshot picture had problem? For this scenario, is it better to create a Mailing list instead?

Thank you in advance.

Regards Jim

The details were given in my question. I am receiving the following message in all my incoming e-mails and have no way of replying to the sender because REPLY and REPLY ALL no longer appear in my Thunderbird e-mail task bar. Here is the message I receive with each incoming e-mail: "A unique identity matching the From address was not found.. This message will be sent using the current From field and settings from identity lonearranger <lonearranger@telus.net>" How can I get rid of this message and go back to seeing REPLY and REPLY ALL in my task bar?

サンダーバードで受信は出来ますが、送信ができなくなりました。 「メッセージを宗しおんできませんでした。 送信（SMTP）サーバー******に接続できなかったため、メッセージを送信できませんでした。サーバーが利用できないか、SMTP接続が拒否された可能性があります。送信（SMTP）サーバーの設定が正しいか確認し、再度試してください。」と表示されます。SMTPサーバーを編集してみましたが治りません。どうすれば良いですか？

My windows 10 Desktop C drive failed, this has been replaced and I am trying to re-install Thunderbird but I can't complete the install due to the error message shown above in my question. Please advise.

My provider changed from q.com email to myctl.net email. I was using outlook but it wasn't downloading new emails. They are on provider web mail. When I downloaded Thunderbird it asked about importing from Outlook and I did. Now it is trying to download the 36,000 emails on the server site and going very slowly and I can't open the ones it has downloaded, I think because it was sent to q.com. Can i uninstall Thunderbird and then set it up again without importing anything?

The user who found she could not run the new version was the user who installed the update. She returned to the previous version (which runs OK). As before the update, server access was via Pop. However her Sent and Local Folders did not appear at all on return to the earlier version and her Inbox now contained only a few recent emails from this year and emails from several earlier years was missing. She set up a second account using Imap in order to be able to retrieve all her incoming mail from the Virgin server but is still without sent mail and her local folders.

Is there any way to retrieve the missing data and to combine the IMap and Pop accounts into one?

We have asked this before, and we still are not able to resolve it at all. Several items: We have two email addresses used by Thunderbird, for many years. [email1]@apaltd.com and [email2]@apaltd.com. Since the last "update", some many months back, her account has had TWO "sent" items/boxes, and they do not have the same items in them as "Sent". We tried to get rid of one, but to no avail. Also, the headings used to have features that showed "dates" in order and other normal things that we used all the time. Now these are gone and we have no idea how to get then back to way to the way opening page was originally, and we are seriously thinking about how to use another service, however we have been happy Thunderbird users for many, many years and need to return the site to its original layout. You folks have tried to help before, but none of the advice worked (i.e, right click on one of the sent boxes to remove it) We are reluctant to simply re-install Thunderbird lest we lose all our other data. We are at a standstill and need advice and help as soon as anyone can help. If any more information is needed, we will happily supply it. Thanking the community in advance for any help/solutions.

Message sent has red texts (all containing an hyperlink). When vizualized in Thunderbird they all appear in blue. When vizualized in Gmail they appear in red! Texts written in red in Thunderbird messages still appear in black in draft's message!

I’ve tried all versions of Thunderbird on my 2020 M1 Mac, and even though I log in correctly, it doesn’t load emails from my account. I used to use Thunderbird normally because I needed it, but I haven’t used it for two months, and now I see that it doesn’t work when I try to connect to my email. It connects to my email normally, but the problem is that when I click on “Inbox,” there's nothing there, and when I click “Fetch Mail” to try loading it again, a message pops up at the bottom saying everything is fine, but in the end, I still don't have those emails. What kind of error is this?

Hello and thank you! When I print emails on our A4 (210x297mm) paper, to which the printer dialog is set, only the bottom half of the header, and top half of the footer, are printed, at the very edges of the paper. This doesn't 'feel' like a printer setting, but more of a Thunderbird setting, for if I set the paper size to US Letter, the footer prints 15mm from the bottom, but still only the top half of the text appears (truncated at the waist). Can you help?

My email was originally set up with Brighthouse which was acquired by Spectrum. My email address has a cfl.rr.com extension. Because of a hard disk problem, I had to reload Thunderbird. Spectrum is still maintaining the old Brighthouse accounts but support is extremely limited.

I can now get into my account in Spectrum's email and can send and receive email there. I had to use a password I set up for Spectrum to do that. But Thunderbird will not recognize my cfl.rr.com account. I can import that account into Outlook and Gmail, but not Thunderbird. It appears to me that Thunderbird is looking for a password that Outlook and Gmail don't require. If I had an old Thunderbird or cfl.rr.com password I have lost it.

I prefer Thunderbird, and I need to get my address book and history files back. I have just set up a new email account in Gmail and imported it into Thunderbird. Is there a way I can I recover my old address book and history files? I do have all the old Thunderbird files that I backed up before I had to reload Thunderbird.
