Thunderbird Community Forum

I have had Mozilla Thunderbird and VPN for some years and no problem but now Thunderbird will not receive or send email if VPN is on. Also there are now a number of sites that will not work whilst VPN is on. I have this on a Windows 11 desktop.

Hi, I am hoping that the community can help me find an answer to this. I have two computers that I use for work. The one in the office has TB running all the time and before I leave for the weekend/vacation I would close TB, copy the profile folder to a USB (or copy it to cloud) and then paste the profile folder on my work laptop (at home). While all the settings get copied (local folders structure, addons etc.) as I use IMAP, it downloads all the mail on the new system regardless. I thought that it should have the latest mail downloaded as part of the profile folder, is that not the case? The bigger issue is that none of the Completed Tasks Lists, Templates, etc. get updated. It still shows all the older stuff on the work laptop and no updates carry over from the PC (at work). Going through the profile folder I see multiple copies of the files prefs.js, folderCache.json, global-messages-db.sqlite appended as: prefs-computername.js and folderCache-computername.json etc. (The computername is the name of the PC - office/laptop) The profile name is the same between the two computers. TB is only started after the profile is copied locally. TB version is the same between systems. I am left scratching my head why somethings are copied but not others. Hoping that the community can help me here. Thanks!

How can I ensure that messages are always saved locally, along with images?

The IMAP protocol works fine now! How can I ensure that images in emails are always saved locally when the internet is disconnected?

How can I avoid constant requests to image hosts when I reopen an email?

I have Firebird Beta installed. I also have Outlook 2019 but after an update the address book is not visible. I have located the pst file(s) but don't know how to import the email address book from Outlook to Firebird Beta. Can you help?

Thunderbird 148+ on Windows 11 repeatedly prompts for the password when synchronizing an Exchange account (professional) configured with the native Exchange support (no add-on installed).

The account only offers “NTLM” or “Normal password” authentication methods. OAuth2 is not available in the account settings.

During synchronization, Thunderbird asks for the password separately for many folders. However, clicking “Retry” usually works immediately without changing the password, and manually re-entering the same password also works.

The issue then reappears for the next folder, causing continuous authentication prompts (I have many folders...).

Actions already tested:

• deleting saved passwords and tokens,
• deleting/renaming key4.db and logins.json,
• restarting Thunderbird,
• recreating the account.

The problem persists.

This looks like an authentication/session handling issue rather than an actual invalid password.

I have several Windows 7 computers running Thunderbird and have 13 POP3 accounts to retrieve. These computers work fine. It takes about 5 seconds to check all 13 accounts if there is nothing new to download. I have two Windows 11 computers that take about 50 seconds to go through these same accounts under the same conditions (nothing new to download). I have done a lot of searching for answers, but nothing helpful has come up. Any ideas on what might be causing this? Seems like it would be a common problem as both Windows 11 computers do the same thing. Both are Windows 11 Pro. Thanks for any guidance.

This happens erratically, not every time. Annoying when trying to select a message to delete and the one before or after or both also deletes at same time. Now I have to go and retrieve it back to inbox. Checked in settings and cant find a solution. Also looked in pad and mouse settings to no avail. Seems to have started in last 2 or 3 months, can't be specific of time line.

I just download the latest version of Thunderbird, and try to add my pop mail account. But after i enter the info of outgoing server settings, the Continue button is gray and can't be clicked. once I try the test, it says that Thunderbird failed to find the settings for your email account. Can't find a server. Also i find that there is no place enter the password of my mail account.

Thunderbird keeps locking up. I have twice uninstalled and reinstalled, yet Thunderbird still locks up with the processing message. At this point, I want to know if 1) there is an online interface that I can try, and 2) If my emails can be salvaged somehow.

I tried the troubleshooting tips on the web, but I can't even get into the folders, even in troubleshooting mode.

My windows 10 machine died on me recently, but I was able to recover all my Thunderbird Email files from the old hard drive. However, the Thunderbird settings I was using under Windows 10 did not transfer over to the new machine and there is one particular issue which is driving me crazy and I don't know how to fix:

Basically, on my previous machine I frequently filtered my emails using the threaded option based on the Subject field. However, under Windows 10 the filter I was using would ignore the "Re:" in the subject line of such threads and so every message in the thread was displayed as if the various instances of "Re:" simply weren't there. However, on my new machine Thunderbird threads messages as if each instance of "Re:" represents a new thread! How do I fix this?

Had to change my ISP password which I did. I then removed all passwords from Thunderbird. I then downloaded the newest version (listed below) After the download I clicked on get messages - no response - did not ask for a password. My ISP pop address is properly listed. I went further and clicked on write - a box opened up asking for a password. Of course I entered my new ISP password and it showed up under saved passwords (smtp etc). I can write and send messages but not receive. I would appreciate a fix to be able to download messages - I miss my Thunderbird. Thank you - I must admit I'm not very teck savvy

I am using Windows 11 with the latest Thunderbird 151.0.1. I have been trying to add color to the column title background in the message list using the userChrome.css with the following:

1. sizeCol {background-color: #dcfffc !important;}
2. recipientCol {background-color: #dcfffc !important;}
3. subjectCol {background-color: #dcfffc !important;}
4. dateCol {background-color: #dcfffc !important;}

1. spamCol {background-color: #dcfffc !important;}
2. fromCol { background-color: #dcfffc  !important;}
3. attachmentsCol { background-color: #dcfffc  !important;}

They work except the 'from', 'attachments' and 'spam' columns title backgrounds. Can anyone see what I am doing wrong? Or is there a way to color all column title backgrounds in one line? Thanks

(If this is a duplicate, please feel free to delete. I posted last night, but the question appears to have vanished from the forum.)

I'm using Thunderbird 151.0.1. After 151.0.0 was installed, the ability to press "/" ("slash") to search while viewing a message was broken. The slash is ignored, and following keystrokes are then acted upon.

If a search is initiated by pressing Ctrl+F, subsequent searches can be started with a slash. It's only when the first search is done that the slash is ignored.

I've been using Thunderbird since the beginning, so starting a search with a slash is in my muscle memory. As a result, I've inadvertently marked or archived or starred messages, navigated to the next thread or next unread message, etc.

Looking at the release notes, I see that a search function was fixed in 151.0.0. I wonder if this is related to that fix?

In any event, can "press slash to start a search in the message window" be restored? ...thanks!

When we first started using a third party application to track our customers information & jobs; we received emails showing the customers name on the correspondent/from column. Now all of the emails show the third party applications name and I do not know which customers are trying to contact us.

Last week I started getting the attached pop-up

I don't use Calendar on Thunderbird (as it does not sync ) Not sure why this has started ..... I have tried putting in password and ticking the remember box - but it still keeps popping up.

I can not get my google workspace account to authorize in Thunderbird. Using IMAP setting. Thunderbird automatically finds the correct server settings, but when I hit "continue", it gives an authentication error.

I have spent extensive time with the google workspace admin console help. This is the final result: "Thank you for trying all the steps so far. Since Thunderbird has already been added under App Access Control in the Admin console, IMAP is enabled, and cookies/cache have been cleared, but the authentication error still persists, this points to a possible issue with the application’s client ID used by Thunderbird for OAuth. In this case, you will need to contact the Thunderbird support team to verify the correct client ID for their OAuth implementation. Once you have the correct client ID, we can then configure it properly in the Google Admin console so the authentication works successfully. We’ve confirmed that all Google Workspace settings on our side are correct, so the next step must be coordinated with Thunderbird’s team."

Therefore, here I am.
