I have recently installed 140.7.1esr (64-bit) on Windows 11

1. It keeps asking for my account password, I always check the box for saving to the password manager, with no effect, I still have to type it in every single time. (I did set up pwd manager and I do have a master pwd)

2. Initially I had Thunderbird pick up my Gmail account as well, but it stopped picking up my Gmail for some reason. So I completely deleted my Gmail account in Thunderbird. yet it persistently asks for access to Gmail every 15 minutes. (I get a notification from Gmail saying that Tbird is asking for access to Gmail). The Gmail account no longer exists in Tbird, does not show up in the menu, and it does not download anything from Gmail if I give it permissions.

I recently re-installed Win 11 with the help of a Dell tool. During the re-install all of my data files were kept, but not the applications. I've re-installed Thunderbird and it works fine. However, I've noticed that my address book is empty. I've found abook.sqlite through the Profile Folder, so I know the file exists, but how do I connect it to the Address Book link in Tools? Thanks Sam

I used to have Windows 10 and was using Thunderbird with Quickbooks POS 18 and if I wanted to send an email in Quickbooks like a purchase order or receipt, it would open up a mailto window in Thunderbird with no issue. I've moved to a Windows 11 computer with the same profile running a 32bit version of Thunderbird, set as my Windows default mail client, even in the registry I've set it there but Quickbooks says I don't have a default email client setup. I've exhausted every search over the internet trying to fix it. Any ideas?

When I try and "Compact" my trash folder, I get the following error message: "The folder 'Trash on redacted@gmail.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

There is plenty of disk space, but there is no option for "write privileges". The trash folder has grown to 632 MgB even though I keep deleting old messages from the trash folder!

I have three email accounts all from different sources.

Two of the three accounts work fine but one account will give me this error message. I back up the Thunderbird folder every week and copied the backup to the working folder and I still have the issue.

I've been getting multiple emails of the same in a few folders. I do have a lot of Filters set up for the account affected.

In previous Thunderbird versions, when you subscribed to a RSS-Feed that required authorization, Thunderbird prompted for it, just as a Webbrowser would.

I'd enter the username and password, tick the box "Save in Password manager" (or something) and the feed would come in.

I don't know when that changed, but nowadays Thunderbird just says "Feed is unautorized". No password prompt, no possibility to mark a feed as "requires Authentication".

I know I could pass username and password in the URL, but that is rather unsafe compared to saving the password in password manager protected with a primary password.

It seems that there were some bug reports some 21 years ago about the same issue, so maybe this is a regression?

My old computer crashed and I have gotten a new computer. It's a Dell All-in-One. So anyway my question is how do I get my email to cross over to my new computer? Also we had LocalTel for a short time and my email and information went through them. My email address was Lorirn@ifiber.tv, they closed the ifiber.tv email system but was still managing it. So when my computer crashed somehow they knew about it and cancelled my email and closed everything. So now I can't get my emails that I had, which was a lot of them. Some were very important to me. I am in a very bad situation. I am hoping that you can help me somehow. I did try your transfer Thunderbird Profile Files and I don't think that I did that right. I have downloaded Thunderbird to my new computer. So I need lots of help from you if at all possible. I am hoping with fingers crossed. I have had to change my email to Lorirn5755@gmail.com, let me know if more info is needed.

Thanx in advance Lori Bolin

Changing color of the text during composing an email does not work when I use "Choose a color" button. The color in the button changes, but when I click "Ok" the color does not change. The color change works though if: I click "Last-picked color", or when I type color name "Green" or HTML hex, and subsequently click "OK".

How to change the color of text in a composed email when

I am using Thuderbird on macOS.

When trying to run in Safe Mode, and compose a new message, I the Thunderbird stucks, so I cannot confirm in Safe Mode, but I had this issue in the past also on other machines/Thunderbird instances, so maybe someone else had a similar problem, or maybe it is a known issue, already in dev team logs.

Hi there,

Is there a way to get checkboxes to select messages or at least a plan to get it in a future release? I saw that there has been an add-on in the past, but not maintained for some years and therefore not possible to use in newer versions. Yes, I know that you can select messages with ctrl and mouse click, but there are others in my family who are not familiar with it and reluctant to get used to it. (have used gmail for too long).

Greetings Grauer

Hello,

Need To Know:

I have used Thunderbird (TBird) for many years. Recently, I moved TBird data from a Dell Inspiron 530 Win 7, to Alien Arora 1250. Unfortunately, the passwords would not go, so I copy and pasted the data for 10 email addresses. All worked well, until 5 days ago when I could not log into the ISP.

Since then, 12 ISP tech support people gave me 12 different was to fix the login problem. The 'logging in' kept trying to login. The only way to stop it is to close TB and restart it. The same happens with all 10 accounts - can't login.

I followed instructions to the letter and nothing worked. Later, a tech at ISP said they have had a lot of complaints from people with Tbird and said it's Mozilla's fault. They all said they don't support Thunderbird. They only support webmail. One even suggested I delete all my cookies. Of course I'm not going to do that.

You would not believe the amount of crazy ideas I was given.

Here is the core problem:

I used both Pop and IMAP depending on the email account. TBird was great with POP and IMAP either.

I changed all the passwords as instructed. I followed the Step-x-Step settings on the ISP web site

The ISP, Rogers, took over Shaw. Rogers, I'm told, dropped support for 3rd party email clients and requires customers to create a new email on their Webmail host. Webmail is WEBmail because it is not Email.

Testing Out TBird:

1. On the old Win 7 TBird (Ver. 68.1.1 (32-bit)) Email works with both POP and IMAP settings.
2. On the new Rig, Tbird (V. 147.0 (64-bit)) worked for a while.

What Happens: -- Due to the issues, I set Tbird to not:, -- Check for new messages at startup -- Check for new messages every -- Automatically download new messages -- Fetch headers only

The two ISP are Rogers Rogers and Shaw <--- just redirects to Rogers. But webmail.shaw.ca still works.

My Rig with the issues: Alienware Aurora Desktop 1250 Intel i9 Ultra Nvidia RTS 5080 Memory 32 GB DDR5 Storage 2 TB SSD + 2Tb HDD Thunderbird Version-147.0 (64-bit)

Is the ISP correct, that Thunderbird may be the core problem?

Thanks for your volunteering - where would we be without you, ~r

I inadvertently deleted a mail sub folder named Shopping Oder Confirmations I found the folder in my acronis backup and copied it to my desktop I then pasted it in to the profile window of thunderbird in hopes that when i restarted it would show up in my mail folders which it did not I can send you screen shots of the different windows where I dropped the folder Can you help please?! There is tons of information in these folders I reference often. Thank you! BTW I did just make a donation :)

Update: Apologies, seems it was my mistake. While setting up the signature in the first place I *did* pick up a named anchor from a template <a name="_MailAutoSig">. It was buried in the generated HTML, and I have now found and removed it. Problem, such as it was, now solved.

Is there any way either to remove the yellow anchor symbol which Thunderbird inserts in front of my signature, or to tell the client not to display the symbol? I didn't put one in the HTML signature that I use. There's no "remove named anchor" command. It isn't related to the double -- marker, which I've already removed using config. I have no use for anchors, which for me are simply a visual distraction.

Thunderbird is so good in many ways (calendar synch is great - one of my major bugbears with Outlook - also recipient privacy when sending out group invitations) and it can be quite frustrating in some others (e.g. unwanted features that I've had to dig around in config in order to turn off)

Thanks everyone :-)

Thunderbird 147.0.1 (aarch64, macos, m2)

Team, After spending many many hours creating 14 search-folders that can find all of the right emails in approx. 20 "real" (local) folders.

Then I renamed 10 local folders and noticed my searchfolders disappearing!?

Big panic. Now, only the last 2 created searchfolders where there. The rest was gone. Realizing that the searchfolder config is in a file called "VirtualFolders.dat" I instantly took a copy. Restart Thunderbird: Now only 1 searchfolder was left. The copied virtualfolders.dat file still had 2 searchfolders in it but the rest is gone. There is no other copy/backup of this file.

These search folders are the only thing that generated some sense in gigantic piles of email.

Does renaming local folders KILL Virtual/Search folders?

v147.0.1 (64bit) = latest I create a template. Template used by "send a new e-mail from template" works fine and send with text and pictures. All Good.

I use a Filter that sends an auto-reply from a Template. Sent message have wrong coding (Poland chars are replace to some strange characters) and no picture in it, at bottom of e-mail are some codes.

Seams of BUG in Thunderbird, a many years ago was z bugzilla for Mozilla products, now I found only that forum.

When I open an email that contains a thread, each response (or reply) shows up in its own window. This results in LOTS of email windows on the screen, and I have to fish around to find the one I want to see. Then I have to close all of them one at a time. How can I change this so the email thread is in one continuous window?
