I set up some custom (number of days in advance) calendar event reminders of my travel plans in my Google calendar via my cell phone. I have my google calendar linked to thunderbird on my pc. I had accepted the invitations before I left on my trip. (looking at the details of the reminder it shows: "You have accepted this invitation.") I returned home from my trip and have several old flight reminders popping up in my pop-up box in thunderbird. I can try to dismiss them, by clicking on the dismiss button, but nothing happens. They do not disappear. But recurring birthday events from my google calendar, which are also in my T-bird calendar, are able to be dismissed from the T-bird Reminder pop-up box. A new event I created today in google calendar, flowed into T-bird with two custom reminders, but no event invite. (Is the issue with accepting invites?) I have tried unsubscribing and re-adding my google calendar, to no avail. I have tried to clear the T-bird startup cache, both with and without being subscribed to my google calendar, to no avail. Any help is appreciated by this confused user, thank you in advance.

Why is this folder SO LARGE !!! C:\Users\xxxx\AppData\Roaming\Thunderbird\Profiles\6v2ccsvd.default-release\ImapMail

On my PC, it is over 3.5GB !

How can I minimize it !

In Thunderbird one of the folders somehow became grey and appears in italics. I can read contents but suddenla not save new files in the folder. What can I do to fix it?

Hi, Has the header disappered in Betterbird? It used to be at the top of each email, with the subject title, and the date and time the email was received. Is there a way to bring it back? Thanks, Des

Whenever I get an email that says they are including an attachment, the attachment is never there. What is going on and how to I get email attachments. Any help is appreciated.

Thank you

I thought I had successful auto install W-10 but when I open to send 1st message the"+ new message" button is not active/working. Per article this is how to start. Thanks for help.

Hello, I am using Time Machine to backup my Mac, but the tool excludes Thunderbird. In settings I have not excluded any files. My Thunderbird folder is fairly large, 25GB - thanks to the great archiving features of Thunderbird, How can I include Thunderbird folder to backups? Thanks in advance for helping. BR Tapio Heikkila

suddenly the Thunderbird cannot distinguish between info@zelec.se and info@stiernbrandt.com. It thinks they are the dsame and if I write the email address in the "Edit SMTP server" as info@zelec.se the same name appears in the account info@stiernbrandt.com. This is a very recent error. I saw todfay that this happen and then TH forbids me to send email from info@stierbrandt.com since it wrongly copies the into the info@zelec.

Hi

Thunderbird is crashing with error message: expected value at line 1 column 1

Error message in crash dialog box: " Thunderbird Crash Reporter Thunderbird had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash. Details expected value at line 1 column 1 Restart Thunderbird | Quit Thunderbird "

troubleshooting so far:

• How often? periodically (sometime within minutes of loading, sometime hours).
• uninstalled, rebooted, reinstalled Thunderbird (using winget)
• created a NEW profile (have to re-download mail / folders ... taking day(s?) ... since when I walk away and come back hoping download has finished but it has crashed) ... not sure when it will get caught up ( main mail file is huge (20+GB) )
• tried: accessibility.force_disabled changed from 0 to 1 (found suggestion in a google search)
• tried: troubleshoot mode (even though I don't use any add-ons)
• I use multiple mail accounts (although currently I'm only using main one, trying to isolate problems)

Thanks for help.

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

Hello, I received an email from Spectrum (.TWC) that I needed to change my password by Nov. 11th. I did change it last evening. Now today I cannot receive my email via Mozilla Thunderbird, I receive the pop up to Enter the Password when I open it.

Then a second submit I added: -I came to search helps as to why I need to add the password every time I open Thunderbird's password. I searched and found something similar to what I am having problems with here: https://support.mozilla.org/en-US/questions/1525666

I removed the password that was there for years, I then shut Thunderbird, retyped the new password and it still does not work, and in the Settings Security Password there is no more the TWC in the list but only the hotmail account I have also in the list. Now I do not know how to ADD a new Password in the Settings Password. I am stuck there. No more emails coming in for two days now.-

Then the third submit I added: -I still cannot set the Password that the support above said to remove, I cannot add a new password and the settings shows that .twc is not on the list any more for Setting Security.

Also once in a while it shows a pop up at the right bottom of the page. I added it as an image.

Can someone please help me with this so I can get my .twc mail back. I tried myself and it does not work, I've read many Helps and it's not the issue that I have.-

I tried the original password, made several new ones and it still not working nor showing the .twc account password in the Settings, Security and Passwords area.

I am at a loss and need TB to work as it was before Spectrum informed that I need to change my Spectrum Password before Nov. 11.

Thank you for your time and efforts.

For years, I have been routing all my Gmails through Thunderbird very seamlessly. Then my computer crashed.

Nothing on my hard drive was retrievable...so I had to download Thunderbird onto my new computer. I then proceeded to move all my Gmail to this newly downloaded Thunderbird. I had many different files in Thunderbird on my old computer, so everything was tidy and easy to find. When I opened Gmail after losing my old computer, I was relieved to see that the files, and the way I had them organized was the same. So, I assumed it would transfer over to the newly downloaded Thunderbird that way.

However, when I moved all my Gmails to the newly downloaded Thunderbird, all 3200+ Gmail emails were lumped into Thunderbird's "inbox".

What can I do to get everything back into their folders like they were before?

Spectrum forced a password change and now I can receive but not send emails from TB. I have spoken with Spectrum support, been through everything suggested on both the Spectrum and TB forums --multiple times-- including deleting and recreating the account, editing the password, checking for typos, blank spaces, changing the TLS security minimum, running in troubleshooting mode, etc etc. and nothing has worked. I have TB 140.4.0esr on a Chromebook with ChromeOS 141.0.7390.135 and Debian GNU/Linux 12, no separate antivirus program or firewall but do have Malwarebytes. The only recent update was to ChromeOS but that was weeks before the problem developed. I have two other (non-Spectrum) accounts set up on TB and they work fine. I can send emails from Spectrum's website but this is not a permanent solution. These settings match those provided by Spectrum, although they only show SSL, not SSL/TLS.

This is maddening. A couple of days ago TB started to freeze. I have not added any new add-ons. I don't even have any add-ons. I tried one suggestion of repairing and compacting folders and that did not help. I also tried the accessibility.force_disabled change from 0 to 1. It is still happening. I have to use Task Manager to shut it down because if I right-click and close it tells me that TB is already running but not responding when I try to restart it. It takes 4-5 tries to get it to the point where I can have a few minutes to do anything in the program. If I leave and come back, the mail window is frozen. Help, please! I have been using TB for years and never had this problem!

Hi Mozilla. For whatever reason I am unable to send to Gmail accounts. This has only been happening for about 4 months. They are all bouncing back. Dont know whats wrong as - to my knowledge I have never altered anything. Please help

My gmail account in Thunderbird has only two folders, the Inbox and the Drafts folder. so when I delete a message, it lines out the message in the inbox with a single line strikeout and then in order to get it out of the Inbox I have to leave the Inbox and then when I come back to it the message is actually gone from the inbox. When I am using my laptop rather than my desktop computer, all of the folders are there and the messages, when deleted go to the "Trash" folder and are removed from the Inbox. I have been looking for a way to get all of those folders that are normally a part of the other accounts that I have on Thunderbird without success. Is there anyone here that knows how to restore those additional folders to the Gmail account that does not currently display them?

To be clear, I seriously doubt the problems I am encountering are TB's fault! The problems may be my fault since I've grown older, I've tended (believed) using new versions of software present my mind a BIGGER challenge than using the older software/version I have been successfully using? I'm still using Version115.10.1

After our ISP chose to start using Zimbra Oct. 7, 2025 and their tech support could not assist me in getting TB working the had me remove POP3 settings for TB and change to IMAP with their software.

FINALLY someone helped me get TB working with IMAP. For 3 days grrr. Now the ISP says I need to use their web mail, Zimbra.

So might downloading the current TB version and somehow get the In box, all the folder contnets etc. over - into the new TB help?

I was going to backup everything tonight, now I have little to NO hope, without help!

THANKS & remain WELL plus be SAFE!

Robin
