When playing a YouTube video and attempting to open a new tab, Firefox consistently crashes. This was also occurring with Picture-in-Picture mode.

Has anyone else encountered this?

I've been running TB for 10-12 years, generally with no problems. When I logged in on 5/13/26, I saw that Windows had run an overnight update:

    2026-05 Security Update (KB5089549) (26200.8457)

Thunderbird (version 147.0.2.0) was not running, although it had been when I slept the PC the previous night.

Now, when I try to start TB it gives me the crash report dialog. Selecting the Restart option just brings me back to the crash report.

In searching for possible causes, I see that this may be caused by a bad profile. So I open the profile folder with (run) %APPDATA%\Thunderbird\Profiles\ which in my case is:

  C:\Users\<user_name>\AppData\Roaming\Thunderbird\Profiles

This is an empty directory. But if I go up one level to \Thunderbird there is a profile.ini file which contains (actual user ID replaced by <user_ID>:

[Install8216C80C92C4E828] Default=E:\Thunderbird\Profiles

[Profile0] Name=<user_ID> IsRelative=0 Path=E:\Thunderbird\Profiles Default=1

[General] StartWithLastProfile=1 Version=2

"E:\Thunderbird\" is the correct location of my TB installation. In that directory is a profile.ini file that contains:

[General] StartWithLastProfile=1

[Profile0] Name=default IsRelative=1 Path=Profiles/<user_ID>.default

Directory "E:\Thunderbird\Profiles\<user_ID>.default" is present. But all of it's files are dated 2010 except Mail, dated 2016.

Directory "E:\Thunderbird\Profiles" contains the ImapMail and Mail sub directories totaling about 25GB data.

I don't know what the Thunderbird startup process is or if this all looks correct. Can someone give me a sanity check? If this looks normal, what else could be corrupted?

Thanks in advance.

I already left a topic here on this issue, then no one could help me, in general, the problem appeared a month ago in me, as after I reinstalled Windows, downloaded the facit anti-cheat steam browser and went to play facit, since facit requires some settings in the bios for it to work, when downloading the anti-cheat, it asks to restart the computer, it asks for tpm 2.0 secure boot , VBS , iommu , and so I thought for a long time what could be the problem that it is after installing the anti-cheat facit that the browser breaks. As a result, I found out that it is when the iommu function is enabled in the firefox bios that it breaks , if you disable this setting, the browser works, although it gave an error before and did not start at all, I spent a month trying to figure out what the problem was, I am a Windows optimizer and I had custom windows and a lot of different settings for optimizing windows, but now I have installed official windows and the problem is still there, it turned out that it is far from in windows and windows optimization, because I have many friends who use custom windows and optimization settings and everything works for them, and so I found out that it's about iommu , just a couple of days ago, I updated the bios, I had the old version, now the newest one is still present, if there is, then help me figure it out.

here is the error code from the "details" by the way, not only firefox breaks, but also chrome, brave, etc.

Après avoir téléchargé la toute dernière version, 18.5.00, firefox ne fonctionne plus. Le message apparait à chaque recherche d'un site : l'onglet a planté. Que faire ? Merci

I have accidentally opened up hundreds of mail I meant to delete. I cannot access my emails, Thunderbird keeps failing to respond. I have tried closing each tab but I cannot tell what is going on. Help please. I can't give the version as it doesn't respond to any instructions

After Windows installed an update in the middle of the night I can't open Thunderbird and I've tried uninstalling it and reinstalling with success.

It says: Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I've rebooted the PC, shut down the PC, ended the task and still nothing. It seem that Thunderbird didn't shut down correctly and the system still thinks that it's open and running. Anyone know how I can fix this issue?

Thanks,

Gregg

When I open Firefox for the first time after logging in to my macbook, after a few minutes, a second Firefox icon appears in the dock at the bottom of the screen. Why is this happening (only started a few days ago)? And how do I stop it?

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

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.

Dear Mozilla Support Team,

I have downloaded Firefox through the official website and I have installed it through the terminal for Chromebook's Debian Linux.

I have a Chromebook c214ma with a Intel Celeron 4020 with 4 GB ram every single browser on my machine works properly just Firefox keeps closing and crashing

Kindly fix this issue

Regards,

Pranav

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'm able to add an e-mail account but when I go to add a second e-mail account, when it looks up the information, it just hangs with the circle going around.

This is true for two different user accounts on the same computer.

I've uninstalled and reinstalled Thunderbird but it didn't help.

Thunderbird can't be exited without killing from the task manager or shutting down.

I need to change some config settings to prevent some problems that corrupt the screen or crash Firefox on android almost every day. I found that using a Bluetooth reduces the frequency of these problems, but it still happens and is very frustrating.

Sadly Thunderbird often hangs, particularly if a network disk goes down. It is a strange hang, with the Inbox shown when hovering the task bar, but selecting it does not open the window. I have been observing this for perhaps 6 months.

In the past, it was sometimes possible to Close Window, else End Task, but neither have any effect. It seems that End Task is disabled.

Consequentky when Thunderbird hangs, the only way to restore Thunderbird functionality is to tidily close all other applications, restart Windows, which fails, hold power button for 5 seconds, then manually start again.

Why isn't Thunderbird killable?

Hi,

At some point in the last couple of weeks, I've started running into very frequent crashes running Firefox in the Linux container on my Chromebook. It previously worked well, but is now unusable. I'm now running Firefox version 147.0.3 on Chrome version 144.0.7559.167. This is after I did a clean reinstall of Firefox using flatpak, which didn't help. It seems like it often happens when my mouse hovers over a browser tab or icon (eg account, extensions, hamburger). Other quirky display behaviour, which mayor may not related, is that videos are often not working (eg Youtube, BBC), and various browser windows (eg when selecting Manage Bookmarks, or restarting in safe mode), open a small size-reduced window. Latest crash reports below -

Thanks for any suggestions.

Lange Zeit habe ich problemlos mit Thunderbird gearbeitet. Plötzlich kommt eine Fehlermeldung und nichts geht mehr: sehr ärgerlich. Ermöglichen Sie bitte umgehend den erneuten Zugang! Mit freundlichen Grüßen Wolfgang Beu

P.S.: Eine Vielzahl von gespeicherten E-Mails habe ich inzwischen gelöscht; daran kann es also nicht liegen!

My Thunderbird crash whenever I tried to "save as" an email, save the attachment of an email, attach a file to an outgoing email.

Every time I did the mentioned, Thunderbird prompts the normal window of my laptop's folders, but it disappear in a second with the Thunderbird crash and quit.

This situation happened after I installed MS365 on my laptop.

I did try the below: 1. Reset attachment directory - mail.compose.attach.dir 2. Run in trouble shooting mode 3. Repair folder index 4. Clear cache

Anyone can help please?
