Thunderbird Support Forum

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

Since some time when I start up Thunderbird I get a popup:

"Add Security Exception" + "You are about to override how Thunderbird identifies this site"

In forums it was stateed this can be due to the antivirus program. I am using Acronis Cyber Protect Home. I closed Thunderbird, pauzed the real time protection and started up Thunderbird again: this did not solve the issue: I still get the pop up, see image attached.

Is there a way to analyse the origin of this pop up? What's triggering this pop up in Thunderbird?

Thx!

I have Thunderbird v115.5.1 and i have no print option available and nowhere to configure a printer. When i hit the PRINT button, my only option is to Save To PDF. I have looked for a Tools option to set up a printer, but there are no options in my GUI

Thanks for the help.

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

Hi, I have upgraded my computer and Thunderbird, however only the INBOX folder is loading.

I have followed the instructions to migrate the folders from the 'Profile Folder' on the old computer, the data has transferred but is not organised as folders, as on the old computer and of course on the main server.

I don't mind if all the data is not on my computer so long as the Folders are there, empty or not but organised in as they are on the main server.

I'm wondering if I selected an incorrect setting while setting up the account within Thunderbird on the new computer.

Thank you and kind regards, Mark.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

bold text All of a sudden today Saturday the 11th Thunderbird stopped sending email on COX but it can receive them. It was working fine then all of a sudden the sending of email stopped. At first I thought that is was Cox being down again, (I've had connection problems this week). But while I was trying to figure it out I received a number of emails. I tried sending a test email to myself usually they go right away but it did not go.

I called Cox. They tech connected to my computer, made some checks, (updated Thunderbird) and after about 20 minutes it started to send messages. 10 minutes later it stopped working AGAIN. This started a four hour telephone marathon with just about every level of service that Cox has. I ended up with Complete Care and while I was on the phone with him and he was connected to my computer the service tech from Cox who was here to check my signal and modem showed up. He tried to look at the problem and could not figure it out. Note I can send and receive mail from the COX email website but and only receive email in Thunderbird.

Cox tells me it is a Mozilla or Thunderbird problem I'm telling them it is not that it is a Cox problem because the server is SENDING me email to Thunderbird but the Cox INCOMING mail server it not connecting to Thunderbird to receive emails. They claim that because I can send and receive on the web page but can not send with Thunderbird. I'm telling them it is a Cox problem.

Anyone else have this issue? Anyone have a solution? I'm shutdown here with over a 25 year history of emails sitting in Thunderbird.

I have established a group in Thunderbird. I want to send a group email to all the individuals in my group. I believe that in the past I could click on the group name in the address book and have all the emails within the group come up in the To line of the email. Now I have to click on the group and then on each individual, which sends their email to the To line, but then when I click on the second person, the email is sent to the individual in the To line of a new email. How can I choose at one time all the emails of individuals in the group?

I just recently downloaded Thunderbird after using Mac Mail for years. Mail suddenly refused to display messages and no one on the Apple forum could figure out why. So I was advised to download Thunderbird. So far, I'm not a fan. Here are my issues: 1. Unread messages in the Inbox are in bold. But the bold is so close to the normal font that I can't tell them apart. Is there another, better way to mark unread messages? A tick/check mark? A coloured background? 2. Messages are automatically organised into conversations. But when the latest message comes in, the inbox message doesn't go bold. So there is no way of knowing where to find it. I have to go through all messages that have a conversation (more than one message in the inbox) and find one where the latest message is in bold at the bottom. It's a royal pain. I see the number next to the account on the left, but nothing is in bold on the right. Grrr. 3. The conversations are the wrong way up. I want the most recent message at the top, not the bottom. I would actually prefer not to have them in conversations at all, just the most recent message, but I realise that is probably asking too much. 4. There is no number next to the Thunderbird icon on my desktop when I get a message. I used to appreciate this in Mail. It told me if it was worth going to my inbox. With Thunderbird I have to open the program to find out. Ok, that's enough for now. I'd better not get started on the shortcomings of the search function, or how to bring the unread messages to the top of the inbox list... There are just too many issues to address is one posting. Thanks for any help you can give.

Hi. I love Thunderbird! But I cannot use a Gmail account.

It all started when I changed the underlying password for my Gmail account (for routine security). I changed the password too on my Thunderbird client for SMTP and IMAP.

But then it popped up with: https://accounts.google.com/v3/signin/identifier?app_domain=http://localhost& [etc]

it keeps giving me this message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

I've tried to read online what's going on. I've deleted the account and tried to set up again, and closed Thunderbird. It keeps doing this. I've checked Google settings ... nothing untoward. It doesn't have a link to Thunderbird still.

What can I do?

Thanks, Dan

I have not had access to my email since the April 18 Thunderbird update, receiving this error message: "After changing password on an IMAP account, the account could become locked due to too many failed login attempts" How do I fix it? Please email me at jjhpor@gmail.com because my primary email, using Thunderbird, does not work (See above) Thank you Jim Housman

My wife and I each have our own Thunderbird accounts. They were created a long time ago, at different times. I’m pretty sure that they were not set up identically. She has recently experienced a problem: the number of new emails downloaded (as shown in the lower left corner of the screen) doesn’t match with the number of new and unread emails listed in the Inbox (the emails shown in boldface). Something else, though I think related: In the upper left corner of the screen, on the same line as the word Inbox, is a small circle with a number inside. I think that number gives the number of unread emails in the Inbox. Her number shows 20 but the actual number (boldface) is 15. Is this a serious problem? Is it a problem at all? If so, how to fix it? Thanks.

Hello, I use Thunderbird with the system default theme (dark on win 11). It is great, and when reading Emails, the background is white. So no mails get messed up. But when replying to mails, the background of the textarea is black and some mails do have black text. So it is impossible to write a mail and keep calm.

Is it in the config or somewhere else possible, to change the color of the textarea to always white / bright?

I do not need any information on how to change the theme for everything to bright as this is not an option.

Thank you!

win 11, 115.4.3 (64-Bit)

I'm running Thunderbird 115.6.0. I used to have a little icon of a cloud, and a button marked New Message (to compose), both just above the listing of mail and local folders in Thunderbird's left-hand pane. Then I clicked on something (that I thought was for something else) and those two icons are gone. I have looked until I'm blue in the face but can't identify whatever it is that will bring these back. Can someone clue me in? Many thanks!
