I-Thunderbird Community Forum

Noticed in LM, the last couple Tbird versions, the context menu doesn't close, when click anywhere on active window, away from the context menu. Happens if R click a message in thread pane, or pretty much anywhere else that R clicking opens a menu.

• Only* hitting Esc key closes it.

Could be a profile issue? (but isn't due to theme used in Tbird - tested several, incl. native w/ Tb package).

Normally, opening a context menu, then L clicking anywhere inside the active window, closes the context menu (how it works in Firefox).

Also, opening a context in Tbird (if don't close it), switch to another app, the Tbird context menu shows on top that app.

Thunderbird is downloaded new messages, but I can only see the Welcome to Freedom screen and cannot click into and see any emails in any folder. I see that numerous emails were downloaded, some going to the inbox, other into the spam folder. However, when I try to view them, all I see is the Thunderbird "Welcome to Freedom" main screen and cannot view any emails in any folders. Clicking onto different emails and their folders all show that same main screen.

Hello Folks,

We are a team of around 15 users who have been using Mozilla Thunderbird with Google IMAP for the last few years. Until recently, Thunderbird has been working reliably without any major issues.

However, for approximately the last one week, we have been facing a serious performance issue with incoming emails. Around 12 out of 15 users are experiencing the same problem.

The main issues we are facing are:

Newly received emails take a very long time to download. After clicking on a newly received email, it takes a considerable amount of time to open and display the content. Emails appear to be downloading extremely slowly, even though our internet connection is a 100 Mbps ILL (Internet Leased Line). The issue is affecting multiple users simultaneously, so it does not appear to be limited to a particular user's Thunderbird profile or PC. We have already tried Repair Folder / Repair Inbox, but the issue persists. We are using Google's IMAP servers for our email accounts.

We are currently using Mozilla Thunderbird 153.0.3 (64-bit) – Meadow Badge.

Could this be a known issue or bug in the latest Thunderbird 153.0.3 update, particularly with Google IMAP?

We would appreciate any guidance from the Thunderbird community/support team on how to troubleshoot and resolve this issue. If there are any recommended settings, logs, diagnostics, or Thunderbird configuration changes that we should check, please let us know.

Since this issue is affecting 12 out of 15 users, it is becoming a significant operational problem for our team.

Any help or suggestions would be highly appreciated.

Thank you.

Thunderbird had been working great for both of us until after my wife stopped checking her emails for a couple of months. When she later opened the program her inbox started downloading hundreds of emails (very slowly) until her inbox contained well over a thousand. I started to delete the unwanted ones but it went very very slowly. I finally whittled it down to a few hundred but the program continues to run very slowly in all phases. In one instance, it took 11 minutes to delete 39 messages. Downloading and sending are not much different. I've done virus scans, checked settings, restarted the computer etc., all to no avail. And when we switch users, my Thunderbird email runs perfectly. I also contacted my internet provider (Spectrum) but they said it had to be a program issue. How can I restore my wife's email to normal function? Thanks, Joe S.

Hello Folks, We are a team of 15ppl using thunderbird from last few year and it work flolessly in these years but from last 1week i have been facing a serious issue of : INCOMING EMAILS TAKING A LOT OF TIME TO OPEN AND READ, fresh email when received and after clicking it takes a lot of time of open, having a 100mpbs ILL speed, out of 15 / 12 ppl are facing same issue, even after repairing the inbox the issue remains same, mails are getting downloaded very slowly...we are using google imap server for the same, need help to resolve the same...is it the bug in the latest update 153.0.3 (64-bit) Meadow badge

I was referred here from Thunderbird Bugzilla report 2081665.

We are experiencing a recurring problem with Thunderbird 153 on several Windows workstations in a business environment.

The important point is that the problem also occurs with completely new Thunderbird profiles created from scratch. It is not limited to migrated or old profiles.

On one workstation this has already happened to three separate Thunderbird profiles.

Typical sequence:

1. Thunderbird 153 is installed. 2. A completely new profile is created. 3. Mail accounts are configured manually. 4. Everything initially works normally. 5. After some time the profile begins to malfunction. 6. Thunderbird Settings no longer open/respond. 7. The address books still exist, but address autocomplete when composing a new message stops working. 8. Creating another new profile temporarily fixes the problem, but the same behavior can return later.

Troubleshooting already performed:

- Troubleshoot Mode - extensions disabled - tested without the existing prefs.js - rebuilt Thunderbird caches and profile UI state - recreated indexes/databases - completely removed Thunderbird from Program Files, AppData\Roaming and AppData\Local - clean Thunderbird installation - clean profile created from scratch - Thunderbird executable and profile paths added to Kaspersky Endpoint Security trusted applications/exclusions

Removing prefs.js from an already affected profile did not restore the Settings window.

A clean test profile initially works correctly.

We have also encountered this behavior on other workstations. Some users have more than 100 message filters and many folders, so rebuilding profiles repeatedly causes significant administrative work.

Several affected computers had Windows user accounts renamed in the past.

We also experienced a separate issue where the Attach File dialog stopped appearing while drag-and-drop still worked. Bugzilla identified this as the already known Bug 2077590, so I consider that a separate issue.

For comparison, after completely cleaning Thunderbird from an affected workstation and installing Thunderbird 115.3.1 with a clean profile, the same workstation currently works normally.

Because freshly created Thunderbird 153 profiles can later develop the same problem again, simply recreating the profile does not appear to be a permanent solution.

Environment:

- Windows workstations - Thunderbird 153 ESR - Kaspersky Endpoint Security - multiple IMAP accounts - business environment

What diagnostic information should I collect from the next affected profile before replacing it?

I can provide:

- Thunderbird Troubleshooting Information - Error Console output - profile file names/sizes/timestamps - Windows Event Viewer logs - sanitized prefs.js - comparison with a working fresh profile

Goodmorning! Since a couple of days, my TH takes ages to download new messages and when I send a message, it takes at least 20 minutes to show in my Sent folder. I downloaded a new TH but the problem remains the same. I have not changed a thing... What can this be? Its enough to make me change the application... I'm on a Macbook M4.

Thunderbird (153.4.0esr (64-bit) ) does not display or let the user change its printer setting before launching print preview from the print command. If Thunderbird is set to choose a missing printer, it gets stuck trying to contact the missing device in order to prepare a print preview. It seems to be stuck forever, it does not seem to time out. There is no cancel button. If you close the document tab, you can permanently lose the document if it is a draft email, unless the email service saves it in a trash folder. The printer setting can be cleared if the user manages to learn how to display and clear the troubleshooting information.

Thunderbird needs to display the printer setting and permit the user to change it before launching the print preview operation. It needs to display a cancel button during the print preview operation.

suddenly it's taking minutes to send an email - if it sends at all. Many times I get a 'failed' pop up window but when I click SEND again it will sometimes go through. Also Some of my emails aren't coming up - only a few of them. And they aren't un-bolding.

Thunderbird freezes when downloading email only from transaction@notice.aliexpress.com

Environment: Windows 11 Pro, Surfshark VPN and Bitdefender Total Thunderbird 156.0 (64-bit), yahoo.ca POP3 account

The Symptoms: Thunderbird stopped downloading emails from my yahoo.ca account with the message "Downloading message 1 of xx" where xx was increasing from one day to the next.

What I Have Tried: I disabled the antivirus and VPN without any result. I searched on internet and I tried the following solution:

 - I deleted the file named global-messages-db.sqlite
 - I repaired and compacted all the folders

without any result. I entered the web interface in my yahoo.ca account and I saw that after the last message downloaded in Thunderbird there was a message from transaction@notice.aliexpress.com. I deleted the message from transaction@notice.aliexpress.com, restarted Thunderbird and it started downloading messages until the next email from transaction@notice.aliexpress.com. I repeated the procedure several times with the same results. Thunderbird downloads any message except messages from transaction@notice.aliexpress.com. For example the messages from promotion@aliexpress.com are downloaded without problems.

I installed Thunderbird 156.0 (64-bit) on another computer I have, using the same environment, with the same result.

Any insights or guidance would be greatly appreciated!

I have thunderbird for many years and now giving me trouble with my email that I get from comcast not letting email to come up says not responding and when it comes up and check the mail and then lower it to taskbar and their is a second copy which I lower it also also please help this is all has started recently and need help badly. If you need more information please let me know

Why is Thunderbird email for PC and Android suddenly loading and syncing so slow this week...very frustrating. I have a gmail email...gmail site is fine. I've compacted all folder, etc and IMAP server server setting for years.

When I write and send a message. A window comes up saying copying message to sent folder and then it won't close. i.e. it just stays there. When I open up thunderbird again it says the message has been sent but I still can't close the window that says copying message to sent folder.

All the emails disappeared from my msg pane (veiw pane) It was fine the first time I used it today, deleted one new message and logged off. Next use ALL msg gone. Folder pane shows they are there. Other computers can see them.

Tried repair folder. Tried DEL MSF. Tried disabling add ons

Can see them in troubleshooting mode but is nasty.

Betterbird site reports this as a known issue in V128.6.0esr (64-bit)

I've use Mozilla since Netscape but "strike a light" it's getting harder to be loyal with the amount of bugs

I have been using Thunderbird forever. Am on Windows 11 using version 128.7.1esr. Dragging and dropping messages to folders no longer works. Frequently it misfunctions, moving folders into other folders and entirely losing emails that then don't even show up in trash or searches. No add-ins are installed. I have tried operating as administrator and then starting. Nothing. Can you help? Am perfectly willing to back up to a previous version if I can retain my saved messages (which are downloaded to my computer and no longer available online).

Unable to open NEW Email on one click. i need to wait for 4-5 mins to open that email. even i am not able to open on one click which contains Barcode. which email contain barcode its also not reflecting in email and even i need to wait for 4-5 mins to open that email.

Kindly help me for this matter i need to change any settings.
