Hello,

I recently upgraded to a new PC from Windows 10 to Windows 11. For some reason I can not open links in any emails, even if right clicking them. I have gone through all steps here: http://kb.mozillazine.org/Standard_diagnostic_-_Thunderbird but nothing has changed. I have disabled Win Defender completely and still no change.

Any idea what I am missing? I am at a loss at this point.

Thanks for any advice or direction.

I am in the midst of the long process of moving most (not all!) of my gmail from the gmail server to TBird, using filters as discussed in this thread.

I've started by first using filters on less important emails (ie so that no true disaster occurs if something goes horribly wrong). As I do so, I have questions!

For example, let's say I use a filter to: copy all the emails from @someone.org to a local folder then delete those emails (from the server)

What happens if one of those emails happens to be within a thread, including emails from people who don't match the filter (ie are not @someone.org). Have I broken the thread forever, ie, has something gone horribly wrong? If so, how do I prevent this behavior/have the entire thread move along with the targeted value? If not, I don't see how I can move email without breaking threads, which is a bit of a problem.

(Also - whoops, I see I should update, but the question remains.)

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.

I get the messgae 'Unable to write email to the mailbox...make sure the file system allows you write priviledges and you have enough disk space.' When I looked at the errors Thunderbird recorded I found thei:

pop3.server1.2: Incorporate write FAILED! Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIPop3Sink.incorporateWrite] NS_ERROR_OUT_OF_MEMORY: Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIPop3Sink.incorporateWrite]

I recently had to restore my thunderbird app as I had issues with my laptop. I do not run Avast...I have tried the 'repair' option in folder properties in thunderbird. Nothing seems to help. I would appreciate any assistance you can give me. I have been using Thunderbird for....well it has been aloooong time and I have never had any issues with it previously. I am running WIn 11 Pro.

I find now that Thunderbird requires Earthlink's password each time an email is sent. Earlier it required it once a day. I am on Windows 11 using Earthlink.net for provider.

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

is there any way to perform a dynamic backup of Thunderbird. By that I mean a regular (e.g. daily) backup of the profile or at least the mailboxes using a scheduler without closing Thunderbird down?

Have been using Juno Email Accounts for past 10 years with Thunderbird Email Client Program for downloading Emails off the cloud. It is now more difficult to make contact with Juno for Tech Support. To do Email one has to have an Email Address and Password ... THEN they need the Incoming Email Server with the Type of server ( POP, SMTP, IMAP ) . Long Story Short it is now Impossible to Install Mozilla Thunderbird onto Win10 Machines.

SIMPLIFY THUNDERBIRD IT IS EXCESSIVLY COMPLEX. I CANNOT EVEN SEE HOW TO MOVE MESSAGES FROM THE INBOX TO THE RELEVANT FOLDER IN MY LIST. I PERSONALLY BELIEVE FIREFOX AND THUNDERBIRD ARE OVERCOMPLEX AND NEED SIMPLIFIED. SIMPLES. WHY CANT I COPY AND PASTE THE VERSION NUMBER. BLOODY ARESHOLES . AS I SAID IT IS BLOODY OVERCOMPLEX. AT THIS POINT I AM CONSIDERING GIVING UP ON WHAT IS CLEARLY AN OVERCOMPLEX PIECE OF SOFTWARE THAT REALLY DOESN'T LOOK GOOD EITHER AND THERE IS NO OFFICIAL SUPPORT SO WILL HAVE TO LOOK FOR AN ALTERNATIVE. COMPLETE WASTE OF SPACE TOO MANY COOKS SPOIL THE BROTH COMES TO MIND THIS IS WHAT WE HAVE HERE

I have been using the same Email Address and Thunderbird for Downloading my Emails for over 10 years. Now Thunderbird will Not Install. Am getting a strange Error Message ... Authentication Error : Unable To Log in at Server. This has happened on 3 machines. Why is it now impossible to Install Thunderbird on Windows 10 machines.

I'm on a new Windows 11 desktop with two monitors. Everything's been working just fine up until around 26th April (two weeks ago) when the native Thunderbird new mail notifications started appearing in my second monitor, rather than my main display. I had made no changes at all myself.

I've been through all the fixes suggested via Google (toggling the displays; checking Windows notification settings), but none of those fixes have made any difference. I switched to using Windows system notifications for a while, but I really don't like them.

Might this be something in a Thunderbird update itself? It just doesn't seem to be detecting the primary monitor at all. All my other app notifications continue to show on the primary display.

Has anyone else encountered this or have any other solutions I could try?

Thanks, Averill

A couple of months ago Thunderbird installed a new version (150.0.2) that made me enter a new identity. After I did that, I tried importing the e-mail folders from the earlier version (139.0), but totally without success. So I tried re-installing an older version, but this also, was no longer able to import the folders stored on my hard drive. What can I do????

Hi , I am using the MacBook Pro M5 which is running with macOS Tahoe 26.5 . I have installed Thunderbird mail with version 150.0.2 . After the initial installation with only one account with few mails in the inbox I found the App opening time is abnormally high & is more than 1 minutes . I have removed the mail App few times & re installed it ( even I have re download the app from net again) , but the problem remain same .

I have removed the old folder & files from - ~/Library/Thunderbird/ , ~/Library/Application Support/Thunderbird/ , ~/Library/Caches/Thunderbird/ , org.mozilla.thunderbird from ~/Library/Preferences/. before the re installation & re started the laptop , but no improvement in results .

Also in mail setting references → Unchecked the option - Enable Global Search and Indexer Disable all Extensions and Themes under Tools → Add‑ons & Themes (No Extensions is installed) .

Just to inform that the apple mail is working fine in this laptop .

After all the above trails the results are same , the app once quit & re start - it takes around 1.5 minutes to open after which the app works normally with out any problem . Please suggest if any solution is available for this problem . Best Regards Gautam Banerjee

I just download the latest version of Thunderbird, and try to add my pop mail account. But after i enter the info of outgoing server settings, the Continue button is gray and can't be clicked. once I try the test, it says that Thunderbird failed to find the settings for your email account. Can't find a server. Also i find that there is no place enter the password of my mail account.

Здравствуйте!

Пытаюсь подключить Яндекс.Почту к Thunderbird, чтобы скачать письма с Яндекса на компьютер.

Проблема такая: при добавлении аккаунта Яндекс.Почты в Thunderbird меня почему-то перебрасывает на авторизацию Google. Возможно, это связано с тем, что ранее почта была мигрирована на Google-аккаунт с таким же адресом и доменом, либо ящик Яндекса сейчас неактивен (он не оплачен, там просто старые письма лежат) — точно не понимаю.

Подскажите, пожалуйста:

Почему при подключении Яндекс.Почты Thunderbird может открывать Google-авторизацию? Можно ли принудительно подключить Яндекс.Почту вручную? Если ящик Яндекса был ранее связан/мигрирован с Google, есть ли способ всё равно скачать письма именно с Яндекса?

Моя цель — получить локальный архив писем с Яндекс.Почты на компьютере. Буду благодарна за пошаговую инструкцию, что проверить и как правильно настроить подключение.

I sent an email to my mechanic today and another site attached a CC to their Website. It is weird I didn't send an email to them support@bloominto.co, yet I received a reply and there was a CC to my mechanic in it.

How is it possible?

Hello, Thunderbird has already imported my Hotmail account. How do I import my Outlook.com account? It was offered to me the first time, to add another one but for some reason, I could not. Thanks
