Thunderbird: форум сообщества

I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

I must have changed something because T'Bird no longer starts. I was trying to copy TB file from Win 10 to a Win 11 PC. That failed because some files could not be copied. But now TB is not starting up. I checked the Start folder and it is in there.

Suggestions please.

I was trying to change the time emails are kept on the server so I went into "Account Settings" and now Thunderbird is locked onto this page. I get a "Mozilla Thunderbird not responding" message when I try and click on anything and I can't get out of this page nor access my Inbox. I've tried starting Thunderbird in Safe Mode which didn't work. I then uninstalled and reinstalled the latest version of Thunderbird but when it starts it goes straight back to the frozen "Account Settings" page. I've checked my profile and there is a new profile that was created with today's date. There is also a profile from June 2025. If the old profile contains all my emails and folders up to yesterday, that would be OK.

New Computer--4 days old Have downloaded Thunderbird (twice, the latest version from Moz website) Thunderbird crashes whenever I leave the computer long enough for it to go into sleep mode Crash reason: EXCEPTION_ACCESS_VIOLATION_READ Troubleshooting gives no answers Now running in Troubleshoot Mode having disabled add ons (none, I believe) Not much running on new computer yet--Avast, DuckDuckGo [I had a browser crash & needed to reload it on day 2 of machine's life (DuckDuck)...which might mean it is a machine issue rather than Thunderbird?...] Help! bp-4f000aa4-9396-4686-9338-49b190250203

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

If there's one thing I can count on, it's that the next version of Thunderbird will be more buggy & unstable that the previous version, and v 140 certainly does not disappoint in that category. It crashes & closes multiple times per day. Any time something else may be using a lot of resources, Thunderbird freezes up and if I click on it, the app crashes & closes. At least the previous just stayed greyed out until it was able to complete the task and didn't crash & close. Great job Mozilla.

Win 11 and Thunderbird 140 not working and I have tried all the things I found on the internet and none of them work. I have tried cleaning my registry and deleted directories and uninstalled thunderbird re-started and it will still not work.

I guess I have to forget thunderbird. It is a shame.

In recent weeks, Thunderbird often hangs when I'm replying to another email and have written a sentence or two. It never recovers, and I have to close the program from Windows.

It doesn't always do this. On a few occasions, if I wait a while, close Thunderbird from Windows, and restart it, the partial is in the Drafts folder.

I'm running Windows 11 24H2, but I've been on 24H2 since December, and this problem is more recent.

Thunderbird freezes/hangs on restart (mac OS 15.4), including in safe mode. I've updated to 137.0.2 from 129 and the same problem occurs. It only displays "Looking up gmail.com" and I get the spinning disk of doom and have to do a force quit…

Starting yesterday 4-3-2025 my Thunderbird email keeps locking up and saying it is not responding. I can close it and open it and then work with it for 2 or 3 minutes and it will start not responding again. This is a consistent problem the last few days. I did check and it said there was an automatic update on 4-2-25. I am not sure if this had anything to do with it but i did go in and request an update about 2 hours ago today. This has not helped as I still consistentaly get the not responding problem. Please advise what I can do to fix this.]

Hello, I hope this message reaches you. I have a Mac operating on OS 10.15 .7. Ever since I upgraded my Thunderbird to the 141.0 version, two things happen: 1) the fans of my Mac start ventilating very soon (and the battery starts going down) 2) when I quit Thunderbird , everything goes back to normal , but 10 seconds after, a window opens reporting an unexpected shut down. I usually click OK , but when I click "report" , nothing happens. Thanks for your help J.C.

Upgraded from Windows 10 to 11 a couple months ago. Since then, TB freezes nearly every time I am composing an email. "Help About" says TB is up to date. Remedies? Or do I have to wait for a new version?

Hello, Here is what I consider a new bug in TB. It goes this way: While I am reading a message in the message pane of the standard window (not in its own window), if messages arrive (with a small ding for me), the message pane I am reading goes BLANK and the message I was reading is deselected. I have to reselect the message I am reading and scroll down to where I was. This behavior is very annoying and did not exists in previous versions.

I hope this helps. Thank you , Alain Damlamian

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

I'm running Sequoia 15.1.1 on an M1 Mac Mini. Never had problems before. TB 128.6 0 esr.

As soon as it opens it crashes.

I have a lot of unopened files in a pop mailbox, going to try and remove them.

It seems to still work on my iPhone. Any ideas?

I M get this working. I'm in a panic. Please help.

Hi - I'm trying to install Thunderbird on my mac to get away from a google workspace account. I've downloaded it a couple times and it crashes immediately after the login screen. Same thing in Troubleshoot mode. It's a work computer so it might have something installed preventing the desktop app from working. Thanks for any help you can offer.

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert

Hello Frinds!

Please help me find a solution to a fatal Thunderbird crash that erased the Inbox folder and its subfolder structure. All emails have disappeared, and the cause is unknown. Tried "View" but did not help. Didn't find any local program tools to restore the before-crash-state.

Here are the details:

1. The incident happened due to a random, uncontrolled cursor movement in the bottom left corner of the program window using the "drag and drop" feature. There was no clicking involved. Or maybe it was a coincidence: happened when Thunderbird was upgrading.

2. The current version of Thunderbird Portable is:128.10.0esr on Windows 10 Home.

3. As a result of auto backup creation on the day of the crash, the backup was overwritten by the corrupted original.

4. The size of the main folder has not changed, so I believe the files needed for recovery are still available.

Is it possible that this disaster is the result of a version update? So so far, Thunderbird worked seamlessly.

Looking for help. So far, I have not been able to find a solution, including with the assistance of AI. Thank you in advance.

Best, Max
