As of yesterday afternoon 1/8/2025 Thunderbird crashes every time it opens. I tried troubleshooting mode, but it still crashes.

These are the last five crash reports I submitted:

bp-b06aee68-741d-4f5a-8bc4-c15230250109 bp-82e871d5-0479-422f-9ee1-c0d3c0250109 bp-de082294-4c7b-48e4-a20e-db4730250109 bp-993f1d6a-4671-47bf-9d9a-5da6a0250109 bp-6b4de7fd-a602-4632-ae48-961690250109

Please contact me at my alternate email account: tvcrider@gmail.com I suspect that I will not received notices when someone answers this thread. I pretty sure my account is tied to my Thundebird email. Thank you, Joe G

Just upgraded to a new system with Windows 11. Avast Security. Installed Thunderbird 128.5.2esr same as on old system. Migrated old emails using MozBackup. Worked great for a day. New emails, archived a bunch of emails to a local folder...

Next day after about 3-5 minutes Thunderbird shows the Hourglass and is not responding. Eventually will go to a greyed out window. I have to kill it with task manager. I noticed that in Activity Manager three calendars were syncing for a long time. Disabled all calendars.

Task manager shows CPU usage but 0 Network and 0 Disk activity. 3 sub processes but only one has CPU. Resource Manager shows CPU and 72 threads. Resource Manager - Analyze Wait Chain - reports "waiting to finish network I/O."

I've tried Troubleshooting Mode. Still froze during Troubleshooting Mode. I've tried moving a large local folder out of the mail folder entirely. I've tried clearing the startup cache. I've tried clearing the system temp folder.

I have a lot of accounts, saved emails and message filters. So I really don't want to start over again with an empty Thunderbird and reset up accounts.

Thunderbird crashes regularly. I have determined that it might be due to RAM. When Quickbooks is open, Thunderbird will crash almost all the time. If I close QB, it is fine. I have an HP desktop w/ 8GB ram. What I don't understand is that it started doing this recently, but never used to crash. Is TB using more ram now since the latest releases? Any insight would be appreciated.

One local folder is showing 13 unread messages.

Scrolling through the folder shows no unread messages.

Clicking the top sort by read/unread button shows no unread messages.

Using the filter button for unread shows no unread messages.

Right-clicking the folder "Mark Folder Read" does nothing.

So, I've been suddenly having a little difficulty with my native junk filter not moving all junk into the junk folder. This issue (which I'm not asking about) led me to repair my inbox to try and resolve it.

I haven't repaired my inbox in a while, so this repair proceeded to duplicate every email I've received since roughly 2 years ago. I think there were roughly 12,000 emails that repopulated into my inbox.

Searching through them, I found that they were all emails that had been filtered into folders using filters I'd created. It does not duplicate any other emails, only those touched by the message filters. And yes, the filters all MOVE emails, they don't copy them to the new folder. (These are folders I've created.)

I tried deleting the global-messages-db.sqlite file, but I ran another repair on my inbox yesterday and it duplicated every filtered email that's come in since the day before. I had been using Filtaquilla and thought that may be an issue, but I disabled it yesterday and ran the repair again this morning, and it duplicated emails from yesterday and today.

Is this a known issue? Anything I can do about this?

Thank you! Debbie

Recently upgraded my Dell computer with Ubuntu 22.04, and with that, upgraded Thunderbird to version 128.6. Since then (a couple of weeks!) I've been struggling to re-create something that I've been using since I started using T'bird about fifteen or twenty years ago, back when T'bird versions were in the low two digits in fact.

Until this new version, I was able to create a *GROUP* entry in the address book, one name (call it "Family", say), add multiple names & addresses, and save it under that name. Time to contact Family, I'd type that word into the TO field, T'bird would call up ALL the addresses I had entered into that Address Book entry, and I'd be able to send to everybody with a single Send command.

Not anymore! Now it's Nope, Can't Do.

How do I get that feature in this new version 128.6? Step by step, please. I've not been able to find this info on this forum --- the new format of which I admittedly find pretty confusing.

Today, Thunderbird crashes every time: after about 10 seconds it disappears. I tried a new installation: I got no download! Didn't find anything in the downloads folder. Although I'd done a donation of 10 €... (too little?)

Suddenly all the items in the inbox have become jumbled. Chronological order has become completely lost. As there are many, many items in inbox (over 400--is this the reason for the problem?), it's now pretty much impossible to find anything. What to do to restore the normal order?

I am unable to access Thunderbird for my emails. On first boot it quickly shows the normal screen for a couple of seconds then crashes and shows a screen for an error report. Any further tries to open it results in just the error report screen which I then allow send to Tbird. I can print the report here if that is safe.

Hello,

I use Thunderbird 128.5.2esr with xubuntu 24.04.

All of a sudden (I haven't changed anything) thunderbird hangs completely after a few minutes running. The process does not react at all, I have to kill it. Thunderbird process is then stuck on 100% load.

Already testet (with no success):

• Troubleshooting Mode with deactivated Addons
• Disabled Global Indexing (with deleting global-messages-db.sqlite file)
• Waiting for 20min (in case thread/process is running a long time)
• Reboot OS

I have no idea what the issue is. Does anyone have ideas? Thx, Hugo

Hi,

I'm running Thunderbird on iMac.

I've been quite meticulously color-coding a large number of my folder icons (under "properties" for each) over the past couple of years, but now all my icons have gone back to that default yellow.

I've tried running in troubleshoot mode, but that makes no difference. So now I've updated to 128.5.2esr Nebula, which purports to be the newest. Still, nothing has changed.

Is there any way I can restore those colors? I could, of course, re-assign them by hand, but it would be a major task offering no guarantee that the icons won't simply switch back to default all over again.

suddenly I am asked for passwords on my two email accounts, and when I enter the passwords, which are correct as I've checked with my ISP...I am not able to access my email at all. Email programme was working fine about three hours ago, and now...well I am continually asked for passwords for my accounts, and then told they are incorrect? I've shut down Thunderbird after reentering passwords, have double checked settings, and had to change IMAP setting to mail. etc., as that is what my ISP has told me to put and have also changed it back to imap, but still cannot access my emails at all.

Please someone help me sort this out, it is doing my head in...and this isn't the first time Thunderbird had done this with password issues either///GRRRR

I have an email which somewhere along the line got dated 2040. It's in a folder which is arranged chronologically, which means that it is permanently (at least for 15 more years) at the bottom. Is there a way to change that?

I have 8 email accounts on Thunderbird, 5 Gmail and 3 Outlook. My newly added Gmail account has stopped downloading email, while all the others still work as they should. I keep getting pop-up messages from Thunderbird “Server imap.gmail.com has disconnected”. The problem started yesterday and only 1 of the 8 accounts. This new Gmail account is transferred from one of my Hotmail accounts. I have 7800 emails on the server waiting to come down. Alfred

How often does Thunderbird check for emails? I have several email accounts and just wondering how frequently Thunderbird searches for new emails. I realize you can manually check for emails.

Thank you for your time and effort.

Hello,

I recently closed a Gmail account and removed it from Thunderbird however it continues to periodically attempt to connect to Google with the deleted account's identity.

Under Account Settings, the account has been removed and the Outgoing Server entry has been deleted. All Saved Logins for the deleted account have been removed. There are no calendars configured for the removed account. There are no extensions installed other than LookOut 6.3 which does not appear to be account-sensitive.

If it makes a difference, I am experiencing this with Thunderbird 128.5.2esr (64-bit) on Slackware Linux 15.0.

Short of burning the profile and creating a new one, I'm out of ideas. Any suggestions would be appreciated.

Cheers,

-d.

It might be a very strange question/request, but I would be extremely helpful to if someone from Thunderbird team export and send the manifest of the App Integration that Thinderbird is using to be able to allow users to use the IMAP API of Microsoft Exchange. The one that defines some permissions, like Microsoft Graph's `IMAP.AccessAsUser.All`.

I've been struggling to setup a working app registration from our internal integration needs, and IMAP authentication is failing, while Thunderbird Enterprise Apps works great. As I couldn't get adequate support for troubleshooting this by Microsoft, my only hope is to try to compare something that's working with the app registration that's not working and analyze what's different.

So if someone from the dev/devops is willing to share the app registration manifest (of course, with any confidential data stripped off), I would be extremely thankful.

P.S. I think the manifest should be accessible at https://portal.azure.com/#view/Microsoft_AAD_RegisteredApps/ApplicationMenuBlade/~/Manifest/appId/9e5f94bc-e8a4-4e73-b8be-63364c29d753/isMSAApp~/false (though I'm not sure that the proper App Registration ID).

Hi,

When I receive emails with links, nothing happens when I click on them. I have other profiles in Thunderbird: it works for them. I click on a link in a messge, it opens my default browser and opens the link in it. But not for my main Thunderbird profile.

Thanks a lot for your help,

I've read a lot of similar problems, but have not seen a solution. So I'm sorry if this is repetitive. In short, one day my vast amount of folders had emails in them. The next day, every one of them were gone from view..

When I click on "properties" for any given folder, it gives an accurate count of emails that are supposed to be there in numbers, but you can't see them. While in properties, the "repair folder" button isn't active. A mouse over says it's supposed to rebuild, but clicking on that and OK does nothing.

I did a global rebuild by quitting Thunderbird, going in to my Profile and deleting the "global-messages-db.sqlite file". Then restarted Thunderbird. The Activity Manager did show that it indexed everything, but nothing still showed up.

I made sure my "view" for both messages and threads were on "all". So that's not it either. I even tried the Troubleshooting Mode, and all it suggested was that I clear my start up cache, which I did. Still nothing.

Meanwhile, Thunderbird is receiving and sending new emails. All filters, addresses and folders are still there. Just nothing in them save the new emails I got today. I'm at a loss as to how to recover the emails the properties says exist, but hiding from me.

Specifics... Windows 10, Thunderbird version 128.5.2est (64 bit)

Any assistance to this somewhat competent user would be appreciated. Thanking you in advance.
