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

Verwalte über Thunderbird mehrere Mailadressen, jedoch läßt sich keine dieser Mailadressen öffnen. Es kommt ständig die Mitteilunbg , 'Keine Nachricht gefunden' . Bei Neustart kommt die Mitteilung Thunderbird wird bereits ausgeführt, und dann erneute 'Keine Nachricht gefunden ' ... !???

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.

thunderbird 140.8.1 will not run unless restart of mac mini ios15.7.4 sequoia. only runs once then will not run email again.

Can I back up to a previous version that did run or is there an issue?

I have never deleted so many emails at one time, around 500. Did I exceed the limits of Thunderbird? I cannot log on. Cannot see new emails. I have been on emailsrvr.com and did verify my passwords. Thank You

I am trying to enter my Thunderbird account to review my emails, however, everytime I click on the Thunder bird icon nothing happens. Please help me to regain my ability to open Thunderbird. I am falling wat behind in my work.

This started last year and I found a fix on google but I can't remember it. It has noiw come back and is driving me nuts. About 2-5 minutes into composing an email thunderbird goes unresponsive and is greyed out. i have waited 30 mintues and nothing happens. It does not happen until after you type the first character into the new email. I have checked user rights on the thunderbird folder and my windows user folder and I have admnin rights on both If i shut Thunderbird the email appears in drafts when i restart, but only from a bit before it froze. I have reinstalled, compacted nothign is fixing it. Using 64 bit 140.3 on windows 11 home.Tried update to 140.3.1esr. no difference. Just about to give up and go to Outlook because I don't write trivial emails and this is a PITA

Every time I open Thunderbird, I get the attached pop-up which I can't delete except when I use control alt delete. It always comes back. How can I permanently delete it? Thanks, Mark

Deleted around 400 unread emails at one time, something not done before. Thunderbird shut down, now can not log in. Do not have backup password or two step authorization. Any hope for getting back in?

Hello! The other day everything worked as usual, and I shut down the computer for the night. The next morning, Thunderbird immediately crashed/shut down when starting each of the 2 profiles I always use. The 3rd profile, which is the default-release running a different email, still seems to work normally. Thunderbird 115.10.1

I have tried Windows (10) safe mode, as well as thunderbird Troubleshoot mode and working offline, but the issue continued to occur.

I'm at a loss now as to what could cause 2 profiles to suddenly cause it to crash. By the way, one profile is for a gmail account and the other one is for an Outlook account, so they don't seem to be related.

In case it helps, there were 2 Microsoft Visual C++ programs installed or updated, and updates to Microsoft 365 and Google Drive just before the problem started. These were all auto updates in the background.

Any help from the Community would be greatly appreciated. Thank you!

Good morning

Since this morning (05/03/2026) Thunderbird freezes within a minute or two of opening the program.

Everything in the program freezes up. I cannot even close it.

I am running Version 140.8.0esr on a Windows 10 PC.

Initially I was getting a pop up warning message that ask me to confirm if I wanted to send an email with attachments of over 20 MB. There were 3 or 4 such messages. I had not tried to send such emails.

I checked the Outbox in Local folders for old messages, but it was empty. I also checked the Unsent messages files in Local Folders in the Profile folder. I deleted the Unsent Messages.msf file to no effect. I renamed and replaced the Unsent messages file. Also no change.

I checked for crash logs but there are none.

I have run out of ideas as to what to try next. Does anyone have any advice?

It's pretty much in the title. My in box freezes up and no emails arrive. Microsoft will drop drop down a box asking me if I want to open THUNDERBIRD and says make sure I'm using a trusted server - app??? I don't understand any of this!

Hello, when I start Thunderird, it appears for a few seconds and then a window pops up saying that a crash has been detected. I've already tried reinstalling the program, creating new profiles, entering Safe Mode, etc. Restoring an older profile from a backup doesn't help, and the error remains the same.

I tried transferring data from the old profile to the new one (a new, clean profile doesn't cause the error), but unfortunately, the data isn't visible in the program, along with the pgp keys and everything else. Manually editing prefs.js using chatgpt didn't help.

What else can I do?

My 140 version of Thunderbird froze and I removed it and downloaded 140 afresh but it will not run. I just get a white screen and the settings button will not respond.

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?

I want to be able to switch a large chunk of my email archive "off" so it doesn't automatically load when Thunderbird launches (and consequently is invisible to search), but then bring it back online whenever I need to search deeply.

My Local Folders weigh in at 15 Gb. When Thunderbird launches, which currently takes a few minutes, Task Manager shows it takes up 1.8 Gb of memory, which I assume includes Thunderbird code plus an index it builds of all the messages in my folders. Not only does Thunderbird slow to a crawl and sometimes freeze up and crash, but this memory load appears to be slowing down my computer as a whole.

I can remove archives from the picture manually now: I can close Thunderbird, use File Manager to move the folders I want to be invisible to a location outside of Thunderbird's ken, and relaunch Thunderbird. And then reverse the process the next time I need to perform a deeper archive search. The fly in the ointment is that moving all those tens of thousands of EML files takes time and increases the possibility of file damage each time. It seems like moving the river to fill a bucket.

Another less than ideal solution now is to maintain two copies of Thunderbird, one for current and recent mail and another dedicated to archive folders. We'd have to perform a search in both Thunderbirds to be sure we'd found all instances of something.

I'd like to be able to simply toggle a local folder's visibility within the Thunderbird user interface.

Ideally, Thunderbird would be able to remove a folder from memory when I toggled it to invisible, increasing response time on the fly. But even if I had to reboot Thunderbird to get new visibility settings to affect its RAM footprint, being able to easily toggle folder visibility would still be a huge boon.

In the user interface, I imagine Toggle Folder Visibility added to the Tools menu. This function would display a checkbox next to each local folder showing its visibility status: checked for visible (the default), unchecked for hidden. It would be necessary to click Save for Thunderbird to act on changed visibility requests. Subsequently, hidden folders would be shown dimmed in the folder tree and their contents invisible. Searches would skip over them automatically.

Your thoughts?
