Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but that the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

Hi,

I installed Thunderbird 140.2.1 on WIndows 11 v25H2 with winget but it autoupdated to release version 144. I uninstalled release version 144, re-installed esr version and disabled Updates in Settings, but it auto-updated to release version. So I uninstalled one more time release version, installed esr 144, disabled Updates in Settings and I set up the registry key DisableAppUpdate at 1 but Thunderbird auto-updated again to release version 144.0

Please, can you tell me what can I do to prevent Thunderbird esr auto-updating to release version ?

Thanks.

URGENT! My emails are from 5 roadrunner.com (former mail.twc.com) New owner Spectrum is closing us out of our accounts. How can I protect my 15 GB of emails?? Will they disappear if I can no longer access roadrunner? I'm not sure if the server will be swept, but it's in the works. Please tell me how I can bulk save these lifetime of emails...fast! Thank you! p.s. I am computer illiterate and very nervous! I will appreciate step-by-step. (I thought I was safe downloading them to my computer with Thunderbird, but now I think I need to do more to secure them locally.....thank you!

Thunderbird 140.4.0 / Win11Home 24H2

For many years now I have had several email accounts 'share' Thunderbird's Global Inbox (Local Folders) and this has worked fine (by the way I'm using POP throughout).

For a long time I have also had a separate email account (call this account A) using its own Inbox. Again, all has been working fine.

Very recently I created a new account (Account B) and directed this to use Account A's Thunderbird inbox (via Account B's Server Settings, Advanced...) and selected the "Include this server when getting new mail" option. All looked fine at that stage (I did not think to go back and check Account A's Server Settings, Advanced...). Under Account B's Copies and Folders I also directed Account B to use Account A's folders.

As I expected, Account B did not have any of its own folders created.

On selecting Account A in the folder pane and checking for emails (via the Get messages icon at the top of the folder pane), only Account B was checked (as evidenced by the status bar messages scrolling through at the bottom of the window). This was most perplexing - had I somehow lost a whole bunch of messages that I knew should be sitting in the inbox at the mail server?

However, I soon found the culprit. Account A's Server Settings, Advanced.... were completely greyed out (and so effectively disabled) - see image attached.

So setting up a 2nd email account to download to 1st email account's inbox disables downloading of 1st email account's inbox messages. No warning of this is given - it just happens behind the scenes.

Is this all a conscious design decision (and, if so, why?)? Or is it simply a bug? Is there a solution / workaround?

Just to be clear, selecting or not selecting "Include this server when getting new mail" option has no impact on this one way or the other - it is the attempted sharing of the inbox that gives rise to the issue.

I recently downloaded Thunderbird. Due to comcast transfer of email to yahoo, I now have a yahoo account with a comcast email address. Using the export.mail.imap.yahoo.com incoming server, I was able to get all my mail into Thunderbird. At some point, I was asked to compact my folders. I replied yes. After that there were only 2000 messages in my inbox. To recover, I had to change my settings for my email address to an incorrect one and then back to the correct address. That started the rather lengthy import process again. My inbox is 3GB. What went wrong and how do I avoid this from happening again?

The option "Apply current view to --- -> Folders and subfolders ..." does not work! It ONLY applies to the current folder and also is no longer active after restart of the program. This is VERY annoying!

I have to add a office365 accounts. Everthing works, until Microsoft's popup window requires to sign in to MS 365.

When I click in "Sign In", nothing happens. The button becomes light blue for some seconds, then turns back to blue again.

The credentials are correct, there is no error message, nothing.

Probably a problem with the popup browser window?

Javascript is enabled. Anything else that could break this?

When replying and using inline comments, any backspace gets turned into a carriage return at the end of the message. If you backspace over the first letter of your reply it throws you to the end of the message.

W10 machine, Thunderbird 140.4.0esr (32-bit)

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.

When I compose email messages, I want them to be plain text only. In older versions of Thunderbird, this worked fairly well, but in new versions, even though the message is sent as plain text, it is not the same text that I type into the editor.

For example, if I begin a line with "> " (greater-than space) to indicate a quotation, Thunderbird will add another space at the beginning. I once tried to send "-- " (dash dash space, a signature marker) in a message, only to find that Thunderbird replaced the space with a non-breaking space.

I didn't ask for that. I want the content of the message that I send be exactly what I type, nothing more, nothing less. No reflowing, no subtle character alternation. Is there a setting to disable those mis-features?

I copied my profile because I had to reinstall TB. When I copied it back, I got all my emails but not my address books.. How can I get these back? Also, I got my emails back but it didn't include the number of each. How do i get these back?

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!

I've been searching for a few days for a solution to Yahoo Mail not downloading to Thunderbird, I've seen other people with the same problem, I've tried different solutions, but at this point I've given up. My Gmail is still downloading but I have to check my Yahoo Mail via a browser. What gives? Why did this happen in the first place?

I have Windows 11, I've updated Thunderbird.

Upgraded from Windows 10 to 11 a couple months ago. Since then, TB freezes nearly every time I am composing an email. "Help About" says TB is up to date. Remedies? Or do I have to wait for a new version?

Every time I want to print an email, the default copy number on my printer menu is shown as 2.

I don't know how, when or why this change [from 1 copy to 2 copies] happened.

I wish to 'reset' the default copy number to 1, so I don't accidentally print a second copy and waste ink, etc.

When I want to print documents stored on my PC, the copy number field on the printer menu is blank, allowing me to enter the number of copies I want - so the issue appears to occur only when I print emails.

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
