Hello -- I'm hoping someone will be able to help!

I'm running Thunderbird 140.9.1esr (32-bit) on Windows 10 Pro version 22H2 (OS Build 19045.6466) with an Intel Core i7 processor.

Thunderbird suddenly started crashing repeatedly since yesterday. It ran long enough for me to install version 140.9.1esr, but still crashes repeatedly within a couple minutes of running the application, even if I don't do anything such as trying to reply to a message.

Please see below what I get in the Windows Event Viewer, pretty much the same for each crash. I have also pasted the contents of the following file (the others mentioned above don't exist).

C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppHang_thunderbird.exe_5d8d3f9d863d0b28eacbd2a393cdc3d04ef559_c250478b_deffcb88-26f8-4204-bffd-7e6fd5a2ea88

I've gone to Troubleshooting Information, I've "cleared startup cache", I've tired "Troubleshoot Mode" and still Thunderbird crashes. There's nothing in Crash Reports.

Any help would be truly appreciated!

Best regards,

Miles Montelius

I've got constant crashes jn last update Firefox 148.0.2 (Desktop). Often it happens when Google Meets launched in browser and i started switch between tabs or another applications.

I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks

I was attempting to use the Pinetools.com photo editing site on Firefox for Android, and it sent Firefox into a crash loop - I had to uninstall and reinstall. I was able to replicate this one more time. Here's exactly how it went down:

• went to https://pinetools.com/add-noise-image
• uploaded and filtered the photo
• "right"/long-clicked it to open the edit in a new tab, which immediately sent Firefox into a crash loop
• uninstalled and reinstalled Firefox when it became clear that closing the app wasn't solving the problem
• replicated the above steps, to the same result
• uninstalled and reinstalled Firefox again.

I have uBlock Origin and Privacy Badger, and reinstalled them both times - is there any chance I could have put my device/info at risk?

good morning , I am using a mac mini 8 gb ram and the latest ios, avg antivirus and vpn. Following the latest ios update in feb/2026 thunderbird opens then locks with a rotating color circle and force quit is needed to close it. Emails are via the imap and smtp protocols, with both not being recognised by the server. Can you help, I need access to files from thunderbird. Can this be done offline, avoiding the server problem. thank you for your help. Jeff

I have followed all the other recommendations with, no luck. I am on Windows 11 and use Eset virus software. Thunderbird is not listed as running it Task Manager, and there is no Profile.lock (think that was what it was called) in the profile directory, and I have deleted the existing profiles and recreated it. I have uninstalled and reinstall Thunderbird, and I have rebooted my computer. I am frustrated and concerned I will loose saved emails and my address book! Help.

my firefox keep crashing when i join google meet and i need to do multitask so i open another firefox windows(private or not) it always crash few second after, i have tried the trouble shoot mode its still crashing, even the new windows from SSO request do trigger my firefox to crash. when the browser crash it does offer me to restore my session

Whilst using TB the screen went white with dozens of little tabs along the top of the screeen with what look like page icons, as the app became 'not responding'. Re-loading didn't help - same screen. Re-starting didn't help. I uninstalled and re-installed TB but it is stil the same. Opening in Windows (11) safe mode produced virtually the same result except for a few seconds I was able to open the hamburger menu and select trouble shooting. Opened in trouble shooting mode showed several alerts of 'failed to connect with servers' (outlook.office365.com imap.gmail.com and Yahoo). Then it shut down as before 'not responding'. When open, TB is using some 80% of available memory., and I can only close it by using Task Manager. I'm a complete dunce at this stuff so, if anyone knows a way out of this hole, please use simple English! Thanks, Jeff

2 months ago, after an update the programme opens then locks with the cursor being a multicolor rotating wheel. All is locked and the only option is to 'Force Quit" to close the programme down. Can you help ? thank you

I use K9mail on multiple devices since eternity. Since the latest update it crashes on an old Galaxy S10 / Android 8 when fetching images (show remote images) or, it looks like, when the message has images.

It crashes on 80% of mails with image. I can provide you with messages that reliably crash (e.g. newspaper newsletter from nzz.ch) and with only one that works (newspaper newsletter from 20minutes.ch) Plain text and plain HTML text messages seem to work fine.

it works fine on all other [android 12+] devices Re-install the current version did not help re-installing an older version from FDROID worked

Help is apprechiated

I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

   Search Mozilla Support for this signature How to read this crash report

Can you please help me ? Why does my Thunderbird email account keep crashing upon startup ? It comes up everytime and after 1 minute it crashes . I receive email but only if it is that 1 minute time frame . It just started yesterday , 3/23/2026.

Hello everyone,

yesterday I got quite a scare. While Firefox was open, a new tab briefly appeared showing the page about:processes, and immediately afterwards the browser closed itself on its own.

At the same time, Chrome was open in the background. When I clicked on Chrome, a prompt appeared asking whether I wanted to allow changes to be made to the system (the typical UAC prompt). However, I’m not entirely sure if this was actually triggered by Chrome or possibly by another application.

I clicked “No” on the UAC prompt and immediately unplugged my keyboard. I recently started using an ASUS ROG Falcata, which is connected via USB.

After that, I ran a virus scan with Windows Defender — it didn’t find anything. I also ran AdwCleaner, which also came up clean.

At first, I suspected the ASUS ROG Falcata (I’ve only been using it for a few days), since it’s almost like a small computer itself and can execute macros, patterns, etc. I was worried about a possible firmware bug or something worse. At the moment, I’m honestly hesitant to plug it back in and am using an old Dell keyboard instead.

Importantly, I wasn’t pressing any keys at the time of the incident.

Now I’m quite unsure what could have caused this.

Is there any way to trace this in Firefox (e.g., via logs)?

And is there any (event) log where I could check what triggered the UAC prompt?

One more thing I noticed: I shut down the PC afterward and turned it back on later that evening. Everything booted normally and is still running fine today. However, Firefox updated itself yesterday from version 148.2 to 149. Maybe that was somehow related (though there’s no indication in the Firefox update history that anything failed or similar).

Hello,

I've noticed that recently that Firefox seems to repeatedly crash on my Xiaomi phone quite frequently. It's a Xiaomi 15 Pro on HyperOS 3.0.7.0, and here are some of the crash reports:
