Thunderbird 社群討論區

Hello,

I'm using Thunderbird in Debian GNU/Linux 13 (trixie).

Version: Mozilla Thunderbird 140.4.0esr

apt package: thunderbird/stable-security,now 1:140.4.0esr-1~deb13u1 amd64 [installed]

The last few weeks I started getting the problem that Thunderbird freezes, it stops responding and Debian (with the default gnome UI) shows a popup window saying "Thunderbird is not responding", then I wait for about 10 or 20 seconds, and then Thunderbird becomes responsive again.

Apparently Thunderbird is doing something that takes a long time (perhaps going through messages to index them for quicker search or something like that, I don't know), something that should be done in a background thread so that the program can remain responsive, but for some reason that heavy work is done by the main UI thread causing Thunderbird to become unresponsive.

This problem has gotten worse over the past few weeks, so I really want to do something about it before Thunderbird becomes completely useless. (At the moment I can still use Thunderbird for like 10 minutes in between the freezing, so it's not yet critical.)

How can I find out what Thunderbird is doing while the "Thunderbird is not responding" is shown?

For example, is it possible to configure some logging or performance profiling that would output to a file some information about where the program spends its time?

Other ideas about how to troubleshoot this?

Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I was able to get into troubleshooting mode, but TB was still unresponsive.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

When I open TB and then open an account, once I click on the inbox nothing happens but if I click on another mailbox like sent or trash, everything works normally so then I can go back and open the inbox. This is random but happens frequently. Mail account doesn't seem to make a difference. Version 144.

Thunderbird just updated to 144.0.1 (64-bit), and now I see a blank area where message list used to be. This true for all accounts and all folders.

I used to see this issue temporarily after compacting folders, but usually (but not always) went away and messages showed up. Sometimes I had to close and restart TB. Now even that wont bring up the lists. I'm dead in the water. And, yes, I did reboot my computer as well. Screenshot of this state attached.

Thanks for any help--it's urgent. Bert

I have the latest 128.13.0esr (64-bit) Thunderbird running on Kubuntu 24.04.

I have several Thunderbird installs with over 10 email accounts on each. When I am in one accoujnt I cannot click on the inbox on another account. I have to first click a subfolder such as Drafts and then I can click on the inbox.

To repeat this open T-bird and a profile with several email addresses. Click on Inbox in one. do something. Then click on the Inbox in another acocunt. Nothing happens. Then click on Drafts or Sent and then on Inbox and you are in just fine.

When replying and using inline comments, any backspace gets turned into a carriage return at the end of the message. If you backspace over the first letter of your reply it throws you to the end of the message.

W10 machine, Thunderbird 140.4.0esr (32-bit)

My Thunderbird (version 115.12.2) is running on a Windows 11 system. My profile has multiple accounts configured as IMAP to multiple email services. I also have the Status Bar and Activity indicator enabled. Randomly, both indicators will show busy for an extended period of time. When I view this in the Activity Manager I see one or more folders hung for 10 or 20 minutes downloading one message out of several. This occurs in multiple accounts and servers.

I have researched this and attempted the fixes presented. I have cleared the cache files and compacted and rebuild email folders as suggested, but the slow update still occurs.

Then I decided to try and capture a ProMon.exe trace to see what is happening. What I found was Thunderbird.exe was spending all of the time while hung access the following file: C:\Users\MyUser\AppData\LocalLow\Intel\ ShaderCache\4a5eb0e65e559fc08e65ecb2fa9d650817ae895582a7a7ede162866d3e47a05a, like it was stuck in a loop.

When Thunderbird is operating normally, it is accessing this file but only for short period of times. Research says that it is ok to delete the files in this folder. I did that and it seemed to help for awhile. But it started happening again.

Does anyone have any idea what could be causing this? Is there a Windows thing to look further into? Any help would be greatly appreciated.

Hello,

same issue as described here: https://support.mozilla.org/mk/questions/1487230 I use: 144.0.1 (aarch64) on macOS 26.0.1 (25A362) (MB Pro M1 Pro).

I am using TB 140.4.0esr (64-bit) on Kubuntu 24.04.

Noticed with `top` utility that there is 40-50% CPU usage by thunderbird process. Spike starts every minute and continues for about 30 seconds.

Turns out, if you are using Blogs and News Feeds feature (RSS), TB tries to update some feed every minute. And if feed is inaccessible, I guess, it tries to do so for ~30 secods, then timeouts.

I subscribed to some blogs years ago. Now couple of them disappeared unfortunately.

When I paused updated for certain feeds, CPU spikes has gone.

Hope this can help someone.

Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

I had to rebuild my Thunderbird profile and all seemed ok. However, I now have a possible download issue. As you can see from the attachment, the blue download indicator is stuck as shown. On the attachment I have also shown the activity indicator screenshots from over an hour and which shows almost no movement. What's interesting comparing my Thunderbird United Inbox with the actual Google inbox, I seem to have all my emails in Thunderbird. Any advice?

This has been consistent for over a week now. One folder brings TB to a halt if I try to open any message in it. I have many folders and many I rarely open so I can't be sure it's just this folder but certainly all other folders seem fine and fast. This particular folder did have many messages in it but I deleted them all, accepting that I didn't really need them. I then repaired the folder but was a bit shocked to find the problem continues. The folder says it is 20.9Mb and that it contains three messages each of 7Mb. That's plausible as it just gets one Email per day from my server with some information. The size can vary quite a lot. I could just delete the folder and recreate one with the same filter rules, or I could delete the filter rules before doing that, or ... what?! Technical is that it is TB 140.3.1esr running on a fairly powerful Kubutu machine with 64Gb and really nowhere near any resource limits. It's pulling messages from the one IMAP server and, as I say, everything else seems fine. Any thoughts welcome, TIA, Chris

Hello,

does anyone observe an issue that Thunderbird [140.4.0esr (aarch64) / macOS 26.0.1 (25A362)] freezes for 5 seconds after sending an e-mail? This is super annoying...

Latest version on W10 desktop machine.

1. Setting to open message in a new window does not work. Insists on making a new tab instead.

2. When Thunderbird window is active, kills attempts to use desktop icons for other programs.

3. Cannot minimize Thunderbird via taskbar. Have to hit minimize(-) from window.

Can any of these be remedied?
