Thunderbird-Hilfeforum

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.

Recently, when I click on Get Messages to download email from Comcast server I receive error messages. One error shows "Login to server mail.comcast.net with username X?X?X failed. Retry, Enter New Password, Cancel".. Second error shows "Sending of passwowrd for user X?X?X did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later" I spoke with Comcast tech support and they, of course, gave me the standard line that I was using a 3rd Party App for email and they could not support that and I could instead use the email on line at my Comcast account site utilizing the antiquated Comcast mail options. They finally attempted to help and after they researched the issue they suggested I change the Server Name setting form 'MAIL.COMCAST.NET' to 'IMAP.COMCAST.NET' and changed port from 995 to 993. I tried making those changes and was not receiving the error statements. But I also was not seeing ANY email downloaded or message indicating TBird was login in the Comcast server. I then changed the Server Name back to 'MAIL.COMCAST.NET' and port back to 995. TBird then correctly downloaded dozens of emails. When I tried to same thing the next day, though, the error problems had returned. Finally, I was looking at Tools>Account Settings and selected Add-ons and Themes in left pane. I noticed Bitdefender Toolbar was enabled under Extensions so I tried switching it to disabled. Voila, the program would once again download emails. But a short time later another try to Get Messages resulted in the errors again. Can anyone answer with changes to connect properly to Comcast for email? Any help would be greatly appreciated.

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?

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.

How can I turn off the threading of my emails? Its driving me crazy as when an email comes in after a short time it disappears into the threads and then I have to open each thread to find out who sent the email. At one stage there were 6 emails noted near the inbox but no new unthreaded message, all went to respective threads. Very time wasting.

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?

My wife is an ardent and long-time Thunderbird user. She has tens of thousands of old emails organized into dozens of folders. Recently she noted that many folders contained scrambled emails. For example, an email titled "The race to re-design sugar" from Sept. 2020 now contained what looked like content from an email from Office Depot. See below for a short piece of the body of the email. Anyway, I ran Thunderbird's "repair folder" function and not only did it not unscramble the emails, it also seems to have deleted any emails prior to 6 months ago. Fortunately I've got her T-Bird profile file backed up daily, so was able to restore the original (but scrambled) emails. Any thoughts? I use outlook, but I've got pretty good PC skills if you need to take me into the weeds. Thanks!

Example of one of the scrambled emails: 'From - Sun Feb 4 12:28:28 2024 X-Account-Key: account5 X-UIDL: AEZHkUhl+QCXZb/zNgpcWOY28vQ X-Mozilla-Status: 0009 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Received: from 127.0.0.1 by atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com pod-id atlas--sbc-production-bf1-7448fd4479-zt82t.bf1.yahoo.com with HTTP; Sun, 4 Feb 2024 20:27:34 +0000 Return-Path: <error@em.officedepot.com> X-Originating-Ip: [20.57.66.208] Received-SPF: pass (domain of em.officedepot.com designates 20.57.66.208 as permitted sender) Authentication-Results: atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com; dkim=pass header.i=@em.officedepot.com header.s=officedepot; spf=pass smtp.mailfrom=em.officedepot.com; dmarc=pass(p=NONE) header.from=em.officedepot.com; X-Apparently-To: xxxx.xxxx@att.net; Sun, 4 Feb 2024 20:27:34 +0000 X-YMailISG: T.w7qP0WLDtIndBfVsii11yVLG9YUwuh8bXrpNWGHf2Ezt9n W35tfL8ReGJq0phUGg1KeSNel41YbOoogg21rDC6q0i7xvo0jIbdikP0kWCS '

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.

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

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.

I found the setting for Global Search and turned it on. I'd like to be able to search all folders (imap and my many local folders). No matter what I put in I get zero results. Is there a time period I need to wait for it to build an index? I found an older thread about this on this forum where someone was told to add a folder to the inclusion list for global search. I have tons of folders, if this is the issue, do I really have to do this for every single folder, one by one, including even my inbox?! thanks

My one iCloud email account has been working fine in TB for months. Today sometime TB (115.8.0) began unsubscribing all but a few of my iCloud email folders, including "Sent", "Trash" &c. All other email accounts in the client are unaffected. I resubscribed all of the folders, but they keep unsubscribing - that is, the subscribe process isn't holding and the folders it retains seem random. All the mail and folders on iCloud.com are intact, but TB will show them (some or most of them) briefly, then unsubscribe all but a few. I've tried deleting the account entirely (including data in Thunderbird folder) and re-adding - the problem persists. I've been bale to solve this one. Anybody?

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.
