After the update to the new version of Thunderbird, it is running slow with "not responding" messages. It takes a few minutes to download emails from Google Mail but eventually works. I run widows 10 on 64bit Del laptop with 8GB RAM. I cannot upgrade to Windows 11 as my system will not support it.

Processor Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz 2.39 GHz Installed RAM 8.00 GB (7.80 GB usable) System type 64-bit operating system, x64-based processor

I now have roughly 100 email icons with no subject at the top of my screen. I have to scroll left through all of them before I get to the last 12 emails with subjects and then the inbox icon appears. When I click on a new email from the inbox, it opens and the email icon tab is all the way to the right. Now I have to scroll all the way back to the left to get to the inbox again!!. The email icon tabs cannot be deleted because the button turns light grey. Is there a solution or do I have to save the profile and uninstall Thunderbird?

I'm using the latest version of TB: 128.4.3esr (32-bit) . . . But, I think I have noticed this on previous versions, also.

I like to Disallow Remote content from loading, for security purposes, and then to select to Allow it or not.

But I notice that if Remote content is Disallowed, when I click to delete the email, sometimes it works as expected, and sometimes it does not. The problem is, it's like it deletes it, but then another copy of the email appears. It will not delete. I have to hit Escape, and then delete it in the list. Then that does nothing. I have to close and re-open TB to see that the email is gone.

This is in contrast to how if I just Allow Remote content, deleting an email always works as expected, but then there is the security risk.

If you get a lot of emails you don't want, it's nice to be able to delete them quickly.

What is hanging it up, if you Disallow Remote content?

I have tried Deleting smart mailboxes and virtualFolders.dat . . . This didn't do anything

My Thunderbird restarts (crashes) repetitively, it is impossible to use it. It started when I tried to mark as read the last message of the inbox of the main account, as it crashed when just selecting that message, I tried other ways to have it marked as read, without success. The last thing I did was selecting all the messages in the inbox and marking all of them as read, and now, I do not get to solve the crash problem, even after marking all the messages as unread again. Thunderbird now enters but crashes in a few seconds, turning it impossible to use it. Does anyone know how to solve it? (It seems to be a little BUG in Thunderbird).

Hi your all,

I have used Thurderbird more than 6 years and it was really good for me without any complaints. However, I updated the email from Supernova to Nebular (128.2.3esr (64-bit) yesterday and I got the following message and I cannot receive any emails now. Fortunately, sending is no problem.

"Sending of username did not succeed. Mail server pop3.mailplug.co.kr responded: invalid command"

I searched the previous similar issues in the forum and I checked my status. However my own was the right one that people recommend.

Receiving Server: pop3.mailplug.co.kr / Port: 995 / SSL/TLS / Normal password Sending Server: smtp.mailplug.co.kr / Port: 465 / SSL/TLS / Normal password

Actually, I am using several pop email apps but I have no any issues on those apps except for the Thunderbird. The problem is Thunderbird is my main app. I am alternatively using outlook but really want to return to Thunderbird. Could you anyone help me out?

Thank you for your kindness in advance!

Most of the time Thunderbird is very slow, taking minutes to log in, minutes to download tiny messages, but sometimes is quick. Sometimes Thunderbird complains the password is wrong, but after three retries it accepts the password. Only occasionally it is quick as I'd expect. This has been happening for several months. I had hopes Thunderbird would find and fix the issue without challenge, but as the issue continues I am now raising it formally.

Hi I'm running version 128.4.3esr.

To prevent my inbox becoming very large I have created a folder called Archive and several subfolders such as 2021, 2022, 2023 etc.

Every few months I move old files from an earlier year into its appropriate subfolders.

I've been doing this for at least 10 years. When a folder is about 5 years old it is deleted.

My problem is that today I'm unable to move emails from my inbox to an appropriate subfolder. I get no response. It simply doesn't work as it used to.

Any suggestions gratefully accepted

Thunderbird would not open so I called a technician who set it back up. I have the icon on my desk to, but it will not open and I have to go back to Tunderbird Set up # 128 and reinstall it. What shall I do. Thank you, Treva

Around 3:15 pm yesterday, I stopped getting emails from Outlook (Hotmail). I can send emails out. When I check activity manager, I see: Connection to server outlook.office365.com timed out Why? I Did not change anything. My settings are: Server Type: POP Mail Server Server Name: outlook.office365.com Port: 995 Connection Security: SSL/TLS Authentication Method: OAuth2

Update (11/18/24 12:58) At 11:00 today all of a sudden, I got all my messages from Outlook (Hotmail), but nothing since then again. I do not know what is going on. Is it the Thunderbird's problem or Outlook's. Outlook support claims everything is OK on their side.

Update (11/18/24) 17:11 No emails are coming from Outlook. I THINK THIS VERSION OF THUNDERBIRD (128.4.3esr (32-bit)) IS BAD. ACTIVITY MANAGER SHOWS OUTLOOK CONNECTION TIMEOUTS FROM 3 HOURS AGO. THUNDERBIRD IS SUPPOSED TO DOWNLOAD EMAILS EVERY 5 MINUTES! I EMPTIED TRASH AND THIS EVENT WAS POSTED TO ACTIVITY MANAGER ALONG WITH 2 OTHER EVENTS SAYING THAT 2 OF MY LOCAL FOLDERS WERE DELETED WHICH I NEVER REQUESTED.

CAN SOMEBODY IN MOZILLA SUPPORT TAKE A LOOK AT THIS RELEASE PLEASE AND SEE WHAT IS GOING ON!!!!!!!!!!!!!!

Bonjour à tous,

J'ai un problème depuis ce matin avec thunderbird. Je n'ai absolument plus accès à la messagerie et ne peux plus rien faire avec l'application (installée sur Mac). Tout d'abord, voyant ce problème, j'ai redémarré l'ordinateur, pensant que l'application s'était mal ouverte. Ensuite, comme rien n'avait changé, j'ai pensé que le problème venait de la mise à jour de l'ordinateur, alors je l'ai effectuée. L'ordinateur a redémarré, seulement, le problème persiste. J'ai téléchargé en double l'application thunderbird afin de pouvoir utiliser de nouveau mes boites mails en faisant bien attention à ce qu'il n'efface pas l'ancien. Le nouveau fonctionne mais pas l'ancien et j'avais tous mes mails en dossiers locaux que je dois absolument récupérer ! L'application fonctionnait très bien vendredi.

Ci-joint une copie de ce qui est affiché sur l'application et donc sur mon écran. Peu importe sur quoi je clique, rien ne fonctionne, y compris sur le menu du haut. Quelqu'un saurait ce qu'il se passe et comment récupérer toutes mes données s'il vous plait ?

I am experiencing an issue when importing `.ics` files into a Google Calendar integrated with Thunderbird. Specifically, when I attempt to import an `.ics` file containing multiple events into my Google Calendar through Thunderbird, only the first event is imported; the subsequent events are not added. However, when I import the same `.ics` file into a local calendar within Thunderbird, all events are imported correctly.

Steps to Reproduce: 1. Open Thunderbird and navigate to the Calendar section. 2. Ensure that a Google Calendar is integrated and active. 3. Attempt to import an `.ics` file containing multiple events into the Google Calendar. 4. Observe that only the first event is imported, while the others are omitted.

Additional Information: - Thunderbird Version: 128.4.3esr (64 bit) - Operating System: windows 11 64bit - The `.ics` file in question has been validated and functions correctly when imported into other calendar applications and local calendars within Thunderbird.

I have researched this issue and found that other users have encountered similar problems when importing `.ics` files into network calendars, such as Google Calendar, via Thunderbird.

Request for Assistance: Could you please provide guidance on how to resolve this issue? Is there a known workaround or a planned update to address this problem? Any assistance or recommendations would be greatly appreciated.

Here, as a sample, the ics structure that I've tried to import: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Your Company//NONSGML v1.0//EN BEGIN:VEVENT UID:event-2@_EXPORT_ICS.xlsm SUMMARY:prova 1

Thank you for your support.

Thunderbird gobbles up too much of my SSD space!

How can I prevent this from happening?

I'm using Thunderbird 128.2.3esr (64-bit) Safari browser Version 18.0 (19619.1.26.111.10, 19619) Macbook Air M2 15" running OS 14.7

See attached screenshot

I've been using Thunderbird for years and never had any major problems until a few days ago. But ever since you automatically installed Version 128.4.2esr on my HP desktop running Windows 11, all I can get from Thunderbird is a blank screen unless I go into Troubleshoot mode. Subsequent automatic installation of Version 128.4.3esr did not help.

Сегодня при попытке настроить свою электронную почту, я столкнулся с проблемой, что thunderbird не может найти настройки для моей учетной записи, хотя всё настроено верно. Мне подсказывают друзья, что могут быть проблемы с моей геолокацией, т.к. я проживаю в Эстонии

since version 12, getting new mail in the inbox fails many times due to: checking server possibilities and then time-out on reaching server. Only on thuntherbird email server. No problem with other email programs. Many other user expierence this.
