Bonjour,

Comment contacter un administrateur Geckozone pour résoudre mon problème de connexion refusée car "nombre maxi de connexions dépassé" : je devais avoir la touche MAJ enclenchée ....

Merci par avance, GV

I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

Suddenly I am getting a pop-up window on Thunderbird asking me to sign in to continue with Mozilla Thunderbird email. It populates my email address and after clicking ‘next’ it says.

‘400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know’.

i cannot send or receive through Thunderbird, at present. Who is the genius out there that can tell me what to do?

Keep getting a message for only some of our email addresses when sending messages. Attached is a screenshot of the message. I have checked the smtp settings and they each have their own outgoing settings and they are linked to the correct user name but some work and some do not. We also are getting an error that requests us to login to yahoo. The yahoo mail popup window opens, we enter the user name and it pops up the Turbify business email popup window (because it is a business email). We again enter the user name and password for the email and it opens an error message blocking the turbify site sayin it is suspicious. We have deleted the email account and then added it back, but it does not solve the problem.

When I receive an e-mail that has a JPEG attachment (Windows 10 Professional 64-bit), Thunderbird opens the JPEG image with Microsoft Photo Viewer. When the image opens, I cannot rotate the image. If I save the image and then open that saved image via the same Microsoft application, the rotate icon in the upper left is operative. Is this due to the permissions in the image being opened by Thunderbird from alt/local/temp? Thanks.

Sometimes I'll get an email that will not open to read. And it is at random doing this.

What I see is this. In Outlook it is shown but will not open. While I get the same email in "gmail", it will open. If I open it in gmail and go back to outlook, it is now open. If I open another email in outlook and then go back to the one that does not open. It will not open again.

Does not make sense, does anyone have a "fix" for this problem? Thanks ahead for any suggestions or solutions.

Shortly after my Win10 x64 ver 22H2 update on tuesday 5/13, my Tbird fails to save any sent message with an attachment to the local sent folder. It is sent correctly and saved with attachment in the IMAP server's sent folder. The same message sent with no attachment will correctly be saved to the local sent folder as it should. In both cases the message "saving to sent folder" is displayed. The TB version was just updated to 128.10.2esr (64-bit) and issue continued as before. PC restarts make no difference. SFC system scan finds no issues. Had no issues with this PC & TB over last 5 years until now. Issue is annoying, since I frequently use the local sent folder to forward messages to additional recepients.

Hi I have been used to Thunderbird responding to my beginning to type recipient names with a list of matches. Suddenly it has stopped doing so. I have checked that all my addresses are still present in the Address Book (relief!), but I note that the Contacts sidebar is completely empty (even the Address Book options are missing). I can't find a setting to correct this, and would be very grateful to know how to revert to the previous good performance. Thanks

Hi. I donate 20 bucks a month to Thunderbird. Love it.

Was wondering if there is a way to disable the "support thunderbird" pop ups that always occur upon launch.

Much obliged.

Suddenly, the conversation view has disappeared from my Thunderbird. This happened in version 128, and I have now updated it to the latest version, 138.0.2, but the problem persists. Previously, if I selected any message and right-clicked, there was a local menu option 'View as conversation' (or something similar - I use a localised version). Now, if I right-click the message, it opens with only two options: 'Open in a new pane' or 'Open in a new window'. No conversation view. The default shortcut (CTRL + SHIFT + O) does not work either.

(I did not change any settings, I only compacted folders and tried to rebuild thir index because the global search did not find existing messages.)

Any help on how to restore this functionality would be very much appreciated! Thanks

A few days ago I stopped getting my mail. I checked to see if the firewall was set to allow Thunderbird. It was. I tried changing account settings. I found out that if I changed Connection Security from STARTTLS to SSL/TLS there was no change. But, if I went to NONE my mail came through. Fine, but I don't want to go on without Security. Any suggestions?

I have an event yesterday with a notification on Google calendar.

I start up email today. Notification pops up. I cannot dismiss the notification.

I edit the event to remove the notification. On Thunderbird - but it won't save. So I go to Google calendar and remove the notification.

On Google calendar, it says I have no notification for this event. On Thunderbird it will NOT let me remove the notification.

Now every time i open thunderbird, the notification pops up. Short of deleting the event (which I do not want to do because I want a record of it on my calendar), there is NO way to make this stop.

I have had this problem pop up periodically for the last 18 months. (Unfortunately, it's getting bad enough with no fix I will need to find a different email/calendar application).

Any ideas how to fix? (Can we get the bug fixed in the code?)

unable to send emails, "the message could not be sent because the connection to Outgoing server (SMTP) mail.alburyathletics.com timed out

Thunderbird opens okay, but does not check for new emails. If you press it to manually trigger a refresh - it does not react. It just constantly says DONE in the bottom left hand corner

Thunderbird(TB) gets mail from Hotmail, my own domain, and gmail. I've use and auto-updated this program for the past 20 years. This is the first major problem I've had. Nothing has changed, ie: updates, new programs, or the like.

TB has stopped retrieving new mail since 05.12.2025. I can send mail but not receive mail. ALL settings are correct. I can go to the original sites individually and all the mail is there. Obviously I can send and receive mail on those sites, but TB will only send mail not receive it. The only thing I have not done is uninstall/reinstall.

Does anyone have any suggestions?

hi 大家好， 我用的是thunderbird115，imap协议收入邮件。我发现我的thunderbird 位置文件夹非常的大有565GB，但是我的邮件占用服务器的空间却只有40GB。我查看了我的配置文件夹里的内容，发现有很多名字为nstmp-数字的文件，有几十个，这些文件大量的占用了我的硬盘空间。想问问这些nstmp文件有什么作用，能不能删除他们，删除他们会对邮件有什么影响吗？谢谢大家。

Whole thing running very slowly. Keeps trying to compact folders, Inbox I think,. Have about 88 000 messages in Inbox. Could just delete older ones, say older than a year. Any simple way of doing that?
