My thunderbird email repeatedly keeps crashing after being open for about 5 minutes or so. Time after time for the past 4-5 days. I have sent reports each and every time but the problem persists .can you please help me I will have no choice but to cancel my account and donation. Thank youbold text

For several weeks (I have a work-around for accessing emails) I'm unable to open Thunderbird. First instance of this was Sunday evening Dec 28. I've attached a screenshot of what I see.

I have uninstalled and reinstalled Thunderbird (twice) with obviously no joy.

Any insights would be appreciated.

Please fully explain any file or procedural references; in other words, please do not assume I lmow what you're talking about.

Thanks in advance.

I have Thunderbird 146.0.1 on a Win11 system, using POP. This setup has been in place from Windows 7, apart from the Thunderbird client version, and has worked up till the end of 2025. About October last year, I opened Thunderbird, and whenever I selected an email, or a number of emails, Thunderbird seems to get stuck trying to process something. The moving blue bar on the bottom right hand side of Thunderbird shows activity, but never stops. Taskmanager shows that Thunderbird is running, and that something is happening, but I cannot do anything with Thunderbird. I can only shutdown Thunderbird using Taskmanager. I have Norton AV installed, but I have turned it off, and the problem persists. I have removed all the emails from my inbox, and moved them to local files, and the problem persists. I have deleted and recreated my profile, and the problem persists. I have deleted the Thunderbird client and reinstalled it, and the problem persists. It doesn't matter if I select one, or twenty, emails, Thunderbird gets locked whilst processing something, and the problem persists. There is no issue with my Email provider, as I have checked using a webmail client. Emails are being processed and delivered from my email provider, and are received by Thunderbird. I would appreciate any suggestions as to the cause, or more importantly, a possible remedy. I have successfully used Thunderbird for many years, and I actively support them, so I am very keen to resolve this problem. Thank you in anticipation.

Ich habe Thunderbird auf meinem MacBook Air von Anfang 2015 geladen auf dem MacOS Monterrey läuft. Sobald ich einen eMail Account einrichten möchte stürzt Thunderbird ab. Was muss ich tun, um diese Abstürze zu vermeiden?

Since i updated to 144 Thunderbird works well once started for a few minutes and then starts eating memory and in a few minutes it uses all system memory (64GB) and when virtual memory is exhausted it crashes

Now using 145 beta with same problem.

Using google calendar and only one plugin (Clippings for Thunderbird), tried to disable plugins, calendar, hardware acceleration, tried to compact folders, clear cache, clear msf with no success

Hi all, I'm experiencing persistent and reproducible segmentation fault crashes with both Thunderbird (versions 140.0.1, 141, and 142 tested) and Betterbird on Arch Linux. The crashes occur consistently within 30 seconds to 2 minutes of operation, making the application unusable.

System Configuration:

• Arch Linux (fully updated)
• KDE Plasma 6 on Wayland
• Multi-monitor setup using DisplayLink/evdi drivers
• Firefox works perfectly fine (no crashes)

What I've Already Tried:

• Fresh profiles (completely clean - crashes persist)
• Safe mode with add-ons disabled
• Disabling hardware acceleration (MOZ_DISABLE_RDD_SANDBOX=1, --disable-gpu)
• Software rendering mode
• Multiple Thunderbird versions (140, 141, 142)
• Alternative client (Betterbird) - same crashes
• Full system upgrade

All crashes show the same signature in libxul.so during startup/operation. The stack traces consistently point to Mozilla's threading/compositor code. Notably, Firefox using the same libxul.so library works without any issues, which suggests this is Thunderbird-specific.

I believe the issue is related to KWin compositor interaction with my multi-monitor DisplayLink (evdi) setup on Wayland. The crashes are specific to Thunderbird/Betterbird and do not occur with Firefox, despite them sharing core libraries. Note that this problem happens on both x11 and Wayland.

I have extensive coredumpctl output available if that would be helpful for debugging. Has anyone else experienced similar crashes with multi-monitor setups or KWin/Wayland compositor issues?

Any assistance would be greatly appreciated!

Once I try to add a new email account and have entered the necessary data, I get the ad that the account will be created. However, the program simply hangs up and remains in that display.

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.

An elderly friend uses Thunderbird on her laptop, and up until recently it has been fine. Then it just sits there and doesn’t show any new emails, just kind of frozen. She can send emails but not receive them.. Previously another friend had downloaded BT software to act as an alternate to access her @btinternet.com emails…. Strangely she hadn’t received any emails for a few days…. I found that her emails were being auto forwarded to an unknown email. I disabled that and her emails arrived and were visible on the BT site. I downloaded the thunderbird app to her mobile and attempted to set her account up , with no luck.

Any suggestions. Should I delete the thunderbird stuff on both laptop and phone and re-install?

Thanks

Good morning,

I want to install my account (GMX) in thunderbird on a mac book air (´11 2015 macOS Monterey 12.7.6) but thunderbird crashes every time, after I put in name, email and password and press enter.

bp-aed6c1bc-6b10-4257-a9f4-434400260101 bp-31c768c4-e099-4d79-8c34-c4ec10260101 bp-e5bdae14-6764-478e-9ce9-391750260101

Can anyone help me please?

Hi, I setup an ubuntu 24.04 and used the default flatpak installation of thunderbird- I believe 146- via the software app, so it took a default option. Worked a few hours, then suddenly one of the 3 email accounts on outlook365 blocked sending, no messages. I tried to use some Delete "Start-Cache" option from thunderbird, and then it was no longer able to to boot, and hung up everytime. I had to delete it completely, and the user profile was gone. Not sure if an issue of Ubuntu 24.04 or of the latest Thunderbird on flatpak..I also have no error logs left, those where also deleted with the deinstallation. Ubuntu should go a version back. I meanwhile found some installation pathes for an ".deb" file and hope that will be more smooth. (I work since many years on thunderbird on my PC & Mac with no such problems ever- so this is very new) best regards, Philipp Fonberg, redacted@gmx.ch

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.

I have recently installed version 146.0.1 on a new computer, was using 115.10 before. I regularly put about 50 emails in my outbox using the mail merge add on and then send them in one go. I have done this very successfully for a long time using my Fastmail email account. Now after sending about 10 of the emails, Thunderbird hangs and I have to restart it to send the next 10. If I send them via my Gmail account it still works fine. I am trying to understand if this is a Fastmail or Thunderbird issue. I would have liked to try it on my new computer but with version 115.10 but cannot do this as it seems that the Profile is different.

Any advice gratefully received.

Thanks Bob

From time to time especially when I make a break and the screensaver starts Thunderbird crashes. There is a split between the taskbar of Cinnamon and Thunderbird. The program doesn't react anymore. The only way to use it is to kill it and start it again. I really don't know why this happens. It is a new phenomenon. Here are my Systeminformation: [code] System:

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

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

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?

Thunderbird repeatedly crashes and locks up the task bar. The now frozen PC has to be rebooted by manually powering down the machine. I am in the release channel and using the latest version.

Dear All,

I am using Mozilla under Windows 10 in combiation with Bitdefender Anti-Virus-SW. Mozilla worked quite well with this combination. Since two day, I am not aware of any updates, I am not ablel to lauch Mozilla (no reaction). I deactived Bitdefender and tried also the protected mode for Mozilla (deactivating any add-ins). Unfortunately this had no impact. I could not find any helpful advice in forums. Prior de-installing and re-installing SW I am looking for additional hints.

Best Regards Jochen
