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.

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?

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?

In general, I like Thunderbird, have used it for years. But if there's one thing that will make me abandon it it's that incoming links are not hyperlinks, they're just text. From what I've read, that's deliberate. If not, how do I make incoming links be links? I'm really ready to move on.

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

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

Hi, we started getting Thunderbird errors on both inbound and outbound messages when everything was fine earlier this morning on both. We are on Windows 10 running the Thunderbird 115.5.0 (32-bit) Release.

Inbound error message: The STAT command did not succeed. Error getting message number and sizes. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later. Outbound error message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) outbound.att.net was lost in the middle of the transaction. Try again.

Are you all experiencing server issues - I don't believe this is a configuration problem on my side?

I recently downloaded and installed Thunderbird but forgot my primary password. Have tried the solutions available at the Mozilla website with no luck. I have also deleted the program and my Mozilla account, and started over from scratch. Still no luck.

I can receive emails but cannot send. The error message I get when sending emails. This began as of the most recent Thunderbird update:

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mjndoug22@me.com>... Relaying denied. IP name possibly forged [70.109.132.97]. Please check the message recipient "mjndoug22@me.com" and try again.

I tried to attach/imbed a screenshot of my SMTP server settings but your Browse button below won't allow the paste.

We have 2 computers set up with Mozilla Thunderbird. On one of the 2, the outbound password was inadvertently changed. on the other of the 2, the outbound email works fine.

On the 1 the password was lost, I saw an option to view the password. I'd like to do that on the 1 that DOES work so I can re-enter the proper password.

Thank you,

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.

I currently use Cox email along with Thunderbird. Cox is going to transfer their service over to Yahoo. Will I still be able to use Thunderbird once the email service is transferred?

I set up a new computer, windows 11, and downloaded the latest version of Thunderbird. On the old computer the spam filter works normal, on the new computer Thunderbird puts a lot of normal mail in the spam folder. Is there a way to set the spam filter to not flag so many emails. I use gmail for my mail server. My iphone also uses the same gmail account and does not filter these messages

I have been successfully using Thunderbird for many years. In the last year or so I have been noticing that occasionally one of my sent emails gets corrupted such that the email body starts showing html text and the email subject header is changed to another email header that exists in the same folder but is unrelated to the email body. When I check the corrupted email from the Gmail web user interface, the email is not corrupted. I tried repairing the folder but to no avail.

I attach an example of a corrupted email below:
