I became a THunderbird user recently to help me transfer e-mails from one system (e-mails sent to my e-mail address being collected by Gmail using POP3) - I have a gmail.com address too which shows all the e-mails in the same Inbox. Google are withdrawing support for Pop3. I am moving to Hostinger which happily collects and displays all my emails on its Webmail service. Thunderbird is a great tool for moving e-mails fro Inbox (and al other folders) from the Gmail to Hostinger. But yesterday it crashed and wouldn't restart = white windows says at the top 'not responding = and Windows Task Manager shows me Thunderbird still seems to be talking to one of my accounts and has 6 other tasks open. I stopped those tasks and closed Task Manager. I have uninstalled and re-installed but it comes back with the same symptoms and same tasks running. How do I stop this and get it back properly again

I've been trying to add yahoo account for several weeks, I type in the email address on the add account function and then I just get a wheel of death and have to force shut the programme, I'm on windows 11.

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?

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

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?

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.

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

Right after typing my email address and pressing "Continue", Thunderbird crashes. I wanted to give it a try after many years of not using it, but then it crashes right at the start.

Thunderbird 145.0 (64 bit) with Windows 11 Pro.

In the message editor window, new message or reply or forward, when I want to insert a hyperlink using either CTRL+K or via the Insert menu, a popup window to insert the link into does not appear, and the write windows hangs. Becomes unresponsive. The only way to close it is by ending the task in Task Manager. I notice a crash helper in the Thunderbird group in Task Manager. Everything is on 0% CPU though.

What went on before this is that I modified the property editor.link_color in the config editor (because links are not readable in dark mode, but that's a different story). I then did reset it to default and restarted TB, then pc and TB, that did not help.

In troubleshooting mode, there is no problem. In normal mode, I deleted the only plugin I had (a theme) I cleared cache, refreshed Thunderbird, to no avail. It's not set up to generate crash reports yet.

I have TB on another machine (W10 Pro), I can copy my profile folder over quite easily.

Any suggestions please?

(I'm on Central European time, it may be a day or so before I respond to replies from the US.)

For about 2 weeks, EVERY time I try to write an email, after typing a few lines or so, the whole window 'grays out' and becomes UN-responsive. I get no error message. Waiting for it to respond doesn't work and I have to close out and re-start Thunderbird. Sometimes Thunderbird will have saved some portion of my email in my 'Drafts' folder, but not reliably, so I have to frequently 'Control + S' - save it to avoid having to re-type the entire message again. Troubleshoot Mode doesn't help, nor does clearing the cache. I've been hoping an update would come up that would solve this, either from Thunderbird or Windows (11), but not so far. Please tell me how I should resolve this - I have used Thunderbird for years (and regularly contribute too) and don't want to have to change to different email client.

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

Ich habe versehentlich mehrere hundert Mails geöffnet, anstatt diese zu löschen. Nun startet TB145 unter Windows 10 nicht mehr richtig. Es friert ein, auch ist die Menüleiste nicht mehr erreichbar. Ich habe auch den abgesicherten Modus Probiert nichts geht. Was muss ich tun um das zu beheben?

Hi

I am using the latest TB build, 144.0.1and have only the British dictionary as an extension, no themes.

Occasionally TB will hang when launched and the Windows event viewer will show this....(added image)_

The friendly xml log within the event viewer...

AppName thunderbird.exe

 AppVersion 144.0.1.0 
 ProcessId 0x6234 
 StartTime 0x1dc51956edcf231 
 TerminationTime 5 
 ExeFileName C:\Program Files\Mozilla Thunderbird\thunderbird.exe 
 ReportId f3ad169f-c629-4357-85ae-7db29d0541f1 
 PackageFullName  
 PackageRelativeAppId  

HangType Cross-process

as noted, this only happens when the email client is launched and will not happen each time. I have tried without the dictionary, as it is so random it can take a while to occur, but that does not seem to make a difference.

I am using Windows 11 25h2

Thanks
