Thunderbird Community Forum

[I am starting a new post because I was replying to someone else's post and it stopped working.]

After updating to TB v.140.0esr (then just now updating to v.140.0.1esr) from v.128esr, I cannot compose a new message in any Local Folders or my main virtual inbox. The +New Message button is there, but clicking it does nothing. It was working for over a decade before this.

However, going into the normal account folder inboxes DOES allow me to click the "+New Message" button and start/compose a new message.

I can still reply to messages in the local and virtual folders, just not start a new message.

I have tried disabling all security software. No luck.

I have ran Help > Troubleshoot mode with no addons. No luck.

When I create a new folder under Local Folders, clicking New Message still does nothing while in that new folder. But if I move that new folder to an existing email account, then go to the new folder, clicking New Message works correctly.

I am on Windows 10. I did use the addon Manually Sort Folders in the past, but not recently.

I ran the Check Error Console (ctrl+shift+J) on TB v.140.0esr. Here is the paste:

I opened Thunderbird and could not get to the inbox or any other folders—it shows only the donations page. This is not okay. I do donate. Not much, not too often, but I do. However, if I open e-mail client and want to use it, then this is not a right moment to asking for donations. Or I should be able to do what I came to do and deal with donations issue later.

If you want users to pay for Thunderbird, it is of course okay, but please let us know in advance, give some time to mull it over and then clear the sheets. It is most inconvenient when this kind of issue is raised when you actually need to do something. And the message is unclear - how often and how much I need to donate (pay) in order to get to use Thunderbird without interruptions?

Thank you in advance and I do like Thunderbird. Just not this approach.

PS. Sorry for my bad English, not native speaker. PPS. Or, maybe this is some error that donations page does not "go away"?

For >20 years I have used Thunderbird as my email reader for various email accounts on my mac laptop. Last night Thunderbird stopped downloading emails from my yale.edu account. I tried removing the yale account and reinstalling it unsuccessfully. See attachment. The Yale IT rep told me that Yale very recently added security features that are probably preventing Thunderbird from working with it. They told me to use the Outlook app. Is there anyway I can get Thunderbird to work with my yale.edu outlook email account?

I installed Thunderbird (T-bird), and on the "Set Up Your Existing Email Address" tab, I entered my Xfinity e-mail address/password and clicked on "Continue". T-Bird is able to find the proper configuration in the Mozilla ISP database. I clicked the IMAP radio button and then "Done". That opens a popup window with the heading "Enter credentials for <my-email-address> on imap.comcast.net, but the window never prompts for anything (a prompt for my Xfinity password is what I expected). Instead I just get a message headlined "Unable to connect", with the subtitle "The connection was refused when attempting to contact localhost". This is followed by three suggestions for why that might be the case. I verified that: 1. The Xfinity site is NOT "temporarily unavailable" - I can log into Xfinity directly and see my messages. 2. My computer's network connection is operational since I can load any website at will. 3. I do have Windows firewall enabled, and I suspect that is root of the problem. How can I permit T-Bird to access the web??? Thanks.

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.

I hope someone answers me in Dutch. I cannot open my mail, because I cannot close the "welkom bij Thunderbird" page, that showed when i opened my mailprogramm. I donated, did not work, still not closing, i started my computer again , did not help. I see new mail is incoming but opening is not possible. I hope that i don't have to install it again.Thank you

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

Since Thursday last week, I've not been able to receive or send e-mails.

I constantly receive the error asking for my password. It's the same for my hotmail account and my two gmail accounts.

Please help.

Carol

Thunderbird stopped working and crashes at startup. It fails also in safemode. Any idea?

This report also contains technical information about the state of the application when it crashed.

Last night (9/23/2024), Thunderbird began presenting a screen (see attached) requiring me to sign in to contine to Mozilla Thunderbird Email. At the top of the screen is a "Sign in with Google" line. However, there is nowhere to sign into anything. My correct email is displayed but no entry for a password.

Clicking "Next" takes you to an Error 400 screen. There is no "Close" button and the only way out of the screen is to hit "Esc," which takes me to my Email account. After a short bit, the screen refreshes back to that " sign in to contine to Mozilla Thunderbird" screen. After one or two more uses of :Esc, I can get back control of my laptop.

Meanwhile, Thunderbird is frozen--mail doesn't update, and any attempt to use T-Bird returns me to the sign in cycle. Win 11; TB ver, 128.2.3esr (32-bit); server security imap.gmail.com, port 993, outgoing server smtp.google.com, authentication OAuth2. I've accepted cookies and javascript and closed my VPN. can't figure what to do next.

When I right click on a document [Show More Options/Send To] Thunderbird email I get the following notice: There is no email program associated to perform the requested action. Please install an email or, if one is already installed, create an association in the Default Programs panel. I've been using TB for multiple years with zero problems, this started when I recently reloaded Windows 11 from scratch (due to a bot virus issue). I have reloaded TB 3 or 4 times. I have also tried creating an association to MapiMail which hosed my Send To link. I had to import a new Send To link from my wifes PC after restoring the registry entry for MapiMail. I have always used the 64 bit version, so the 32 bit version is not for me. I am out of ideas? Anybody else have this problem?

I was using Thunderbird for Windows 10 normally for many months. Recently, whenever I launch the app it immediately freezes, and I have to force quit the application. Reinstalling the app does not fix the issue. I haven't tried deleting my profiles yet, but I would like to avoid that if possible.

A couple of months ago Thunderbird started being very slow in multiple situations. I use POP3 and download all mails. I have fairly big mailboxes, some of them up to 2½ GB.

1) Downloading e-mails is slow.

But the worst is this one:

2) Clicking on unread mails first time. This can easily take 10 secs, where the app goes "not responding" and finally "Loading message...." With 10 new mails, it is a lot of wasted time.

3) Dragging mails from one mailbox to another Some of the same behaviour as above.

I have tried to compact mailboxes, but that doesn't help.

I am on release 128.4.1esr (32-bit), windows 10.

I have used Thunderbird for years without issue. In the last 2 days, it keeps crashing on one of my laptops (fine on the other). I sent a crash report, but I can't reopen Thunderbird. I tried both quitting and restarting. I shut down my computer and restarted it. I tried updating by downloading the latest version, but that didn't work either. I completely uninstalled it, reinstalled it, and it worked for a few hours. Now, it is back to the Crash Report.

Any suggestions? I love TB and don't want to switch to something else.

I've updated my MacBook from MacOS 14 to 15.1.1 and it seems to have broken CardBook 97.5. I've checked for updates to the add-ons. I'll get in touch with the developers as well. Has anyone else experienced this?

Thunderbird v128.4.3ser (32-bit) setup with 4 accounts: Shaw.ca (POP), Shaw.ca (IMAP), 2xGmail (OAuth2). The Shaw.ca (POP) account is the main one, and it stopped receiving email. Another (related?) issue is that Local Folders does not appear. The size of that one Inbox is 4.0GB, which I understand is a limit. I don't want to delete any of that email, but I'm fine with moving/archiving some of it. I moved a whack of it to an Archive folder, but the size of the Inbox and Archive folders don't change (4.0GB + 0.0GB). I have tried repairing and compacting. What can I do? I'm a technician/troubleshooter with many years of experience with Thunderbird ... I recommend it to all 6000 of my clients, because (until now) it is bulletproof.

Hi,

Starting less than a week ago Thunderbird has been running slowly. Sometimes it's quite noticeable and sometime not so much. E.g. clicking on a different folder sometimes happens immediately and sometimes takes maybe 4 sec. to display the folder. Clicking on a message sometimes displays it immediately but can take 7 or 8 secs. to display. Receiving messages seems normal and I haven't noticed slower speeds sending. Clicking on Reply for a message can take several seconds, and dragging a message to a different folder can do the same. Once I'm editing a message the edit speed is normal with no slow down and the address book and editing filters are both fast. I didn't make any changes to Thunderbird, this just started happening on it's own.

I'm running Thunderbird ver. 128.4esr (32-bit) on a windows 10 desktop PC using POP to access messages. I ran Compact on all the folders to no benefit. I don't know what else to try.

Please let me know how to correct this or figure out what's going on.

Thanks, Mike
