Before I updated to version 140.0.1esr, I was able to change the background color of my email. I tried Settings>Composition>HTML Style and unchecked use reader's default colors, but that did not work.

when I try to run Thunderbird it opens with my folders but the comes up with the message "Login to server imap.gmail.com with username scoteng1961@gmail.com failed." I exported my details then used the thunderbird uninstall program. then reinstalled it. but problem persists. What password is it asking for and how can I get a reminder of it or a chance to change it?

I need to backup Tbird so that I can reset my PC, then reinstall Windows 11 and all applications. (There is malware that I and Tech Support have been unable to find.) I am familiar with the procedure for moving my profile to a new PC and have successfully executed it before. However, my installation is a little different. In addition to saving / restoring my profile, I also have to set the Local Folders parameter from the Account Settings menu, pointing the Local Directory to files on my HDD. I also seem to remember that the order that this is done relative to copying the profile matters, but I can't remember the details. Can someone help me out?

Hi, I have been using Thunderbird for many years. I have not made any changes to the standard Windows 10 version.

Suddenly, when I want to open a New Message, the button is highlighted in blue but nothing happens when I click on it.

Hi everybody,

Thunderbird is not download mail to the client inbox. I created the mailsadress today, freshly installed TB too. I set up the outlook.com account in TB and TB is establishing a connection with the mailserver, but not loading the mails. every time it tries to connect I can see TBgoing through the motions in status in the bottom left. There are mails in the accounts inbox,TB is just not downloading them. I also tried sending mails a mail to myself, from within TB, works fine. The mail sent via TB arrived in the acount inbox, visible in the webapp.

Please help, THX

already double checked Server Settings:

   IMAP:
       Incoming Server: outlook.office365.com
       Port: 993
       Security: SSL/TLS
       Authentication: OAuth2
   SMTP:
       Outgoing Server: smtp.office365.com
       Port: 587
       Security: STARTTLS
       Authentication: OAuth2

After the latest update, when I insert link and fill out both fields the href is not being populated in the anchor tag rendering the link inoperable. I had to hand code the HTML to send a link to my customer.

I was able to load 1 email perfectly but the 2nd email from the same cPanel will not work. Auto detect and manual settings result in authorization error. The email password is my cPanel login so would be the same for both. Any ideas?

I copied both local Thunderbird file and roaming Thunderbird file, removed everything and reloaded Thunderbird Eclipse. I still cannot access the account on Yahoo mail.

Hi: I need to import my data shown here: C:\Users\DonB\AppData\Roaming\Betterbird\t70e12zz.default\Mail\pop-mail.outlook.com so I see all my email and its folder structure.

I think Outlook.com became: outlook365.com?

Where do I change this stuff so it works?

As soon as I open Thunderbird, the program freezes before I can click on anything. The password prompt box appears, but regardless of whether I click “Cancel” or try to enter the password, the program freezes and only displays “No response.” I am unable to click on any menu item, as the program freezes even then. I wanted to repair it via Windows, but only the “Uninstall” tab appears in the Control Panel, not “Repair”... It doesn't matter whether I start Thunderbird in safe mode or normal mode. The problem is the same. Version: Thunderbird x64 de 140.0.1 Does anyone have any idea how I can access my emails, which I urgently need? Many thanks! Ekki

Hello Mozilla,

I have used Thunderbird for a long time but recently my contact with eBay has worked but i cannot access any choices they give me. Access with Chrome is great but I prefer Thunderbird so can someone please sort this problem.

Starting yesterday 4-3-2025 my Thunderbird email keeps locking up and saying it is not responding. I can close it and open it and then work with it for 2 or 3 minutes and it will start not responding again. This is a consistent problem the last few days. I did check and it said there was an automatic update on 4-2-25. I am not sure if this had anything to do with it but i did go in and request an update about 2 hours ago today. This has not helped as I still consistentaly get the not responding problem. Please advise what I can do to fix this.]

Når jeg laver en videresend af en mail, bliver de tekniske data vedrørende den videresend mail vis i den nye mail. Se vedhæftet screen shot. Inden jeg installerede den seneste opdatering skete det samme ved: svar mail, videresend mail, print mail. Efter opdatering at Version 140.0.1 | Released July 9, 2025, har jeg ind til nu kun konstateret at fejlen kun findes ved videresend. Mvh Michail

I can't send any emails with my personal outlook account. It always says "Login to server smtp.office365.com with username xxx@outlook.com failed." Receiving mails works fine. Both my IMAP and SMTP authentication are set to OAuth2.

Here's my account info found in troubleshooting information.

   account14:
     INCOMING: account14, , (imap) outlook.office365.com:993, 3, 10
     OUTGOING: , SMTP.office365.com:587, 2, 10, true

I've tried:

• Removing and re-adding the account
• Deleting oauth2.issuer and oauth2.scope in config editor and re-login
• Adding the account in a new profile
• Switching to basic authentication for SMTP

They don't solve the issue.

When I click on a folder with multiple messages, each of which has a thread with multiple messages, all of the threads are automatically expanded. If I collapse each message thread, leave that folder, then return to that folder, all of the message threads are again fully expanded.

Is there a way to stop this automatic thread expansion each time a folder is opened?

This morning I opened Thunderbird and a Google Calendar reminder popped up. I clicked 'Dismiss' but the reminder did not disappear. I tried clicking the X close button but the reminder did not disappear.

The problem is that this prevents all access Thunderbird. Nothing is selectable so I have no access to my emails or to any of the Thunderbird settings.

I tried reinstalling Thunderbird (without deleting my profile) and the Google Calendar reminder pops up again.

So I am really stuck!

Can anyone help solve this issue please.

Hi I have a company email account with a large amount of emails accessible from several computers. I created a local folder in Thunderbird on my NAS drive and directed the locations to it on my computers. I have emails sorted by year, as well as received and sent. When I open the program, I can see the email subject, recipient, and date. However, I can't open any of the messages; both the quick preview and the separate window show a white background. What's the problem?
