Exported address books and lists from 115.12.1 (32 bit) on W8.1, importing to 115.11.1 (64 bit) on W11.

Importing a named list into personal address book works - but the list itself is lost; they all go into one big address book. If I choose Create a new folder they all go into that - but again I've no list name, I can't write a message to the list like I used to be able to.

I can select New Mailing List, give it a name, but now I seem to have to enter each one individually, I see no way to paste in a list.

What am I doing wrong please?

I've been accessing ATT.net along with gmail.com for years now. Every once in a while, ATT don't accept my login password? Error message reads: "Login to server inbound.att.net with username pennsynut@att.net failed." And when I "enter new password" with the password from ATT.net, it still don't accept it. I vaguely remember doing something with ATT.net years ago. But why does it keep doing this "login failed"? I ask because if I wait a day, it will re-insert itself. When I check passwords in TB for ATT.net. All it shows is "mailboxc//(mailbox://). The gmails show smtp, imap & oath. But ATT only shows that one. ? How do I get the other passwords in there?

I had a POP account on my desktop PC for many years. Recently I purchased my first laptop and decided to go IMAP on it, while retaining my old downloaded emails as an archive on my old desktop PC. I turned off automatically downloading emails in this desktop PC's POP instance of Thunderbird.

(The desktop PC is Windows 10, the laptop is Windows 11.)

I didn't want to transfer these old emails from my desktop PC to an IMAP server, because they weren't organized -- everything was in the Inbox. On the new laptop (and/or on the IMAP server), I am diligent in putting emails into appropriate folders.

My question is: how can I convert the desktop PC to be IMAP while yet retainomg my old email archive, so that I can access those old emails as needed on both desktop PC and laptop PC -- which will both be IMAP?

Unable to fix the side by side error, my only option may be to re-install Thunderbird or migrate to Outlook.

My question is whether its feasible to re-install Thunderbird and still preserve my old profile and emails. I haven't done any backups of Thunderbird but do still have all my emails on the server.

Thanks Lance

PS I have tried all the suggested fixes as shown in the following link to the side by side error: https://support.mozilla.org/en-US/questions/1439559#answer-1659630

I Have Had It Installed On Microsoft Edge For About A Year With No Problems. I Had It Installed For About 3 Months On Firefox Then I Needed To Install It Again & I Get The Above Messages. Why Is It Doing This? There Hasn't Been Any Harm Done To My Computer. Also Firefox Needs A Customer Service Phone Number For People To Call & Explain Their Issues It's A Lot Quicker & Easier To Solve Your Problem.

Firefox stopped launching from the desktop. After reinstalling the new 127 both once with the 64bit, windows 10, English. The with the 32 bit version as well with the same configurations.

The problem is that the browser will not launch from the install finish window or the short cut icon. I can start Firefox from the Search window > Firefox > run as administrator. Firefox will start up but will not google search and the settings button will not function. I have installed Google Chrome and am sending this message through them. I don't want to use Google for all the reason for privacy that you already know. HOW can I get Firefox back ? Thank you for any and all help you can offer. My Best Regards, Doc'

I've had thunderbird running on my desktop for many years. I tried setting it up identically on my android and it doesn't work. I'm not sure what I'm doing wrong as I run the server side as well. How do you get thunderbird to accept no username or password for the outbound server? I'm using postfix and it only accepts outbound email from my ip address.

I have received an email from Microsoft advising that from a date in September third party apps will no longer be able to access outlook email accounts. Does this mean I will no longer be able to use Thunderbird - which has been my preferred email client for many years? Thanks Nigel

Hi, Set up a thunderbird account on advices from experts due to current issues with BT Email in UK. Have set up an account which is working but the contacts are corrupted? In personal address book loads of hash tags and symbols with no details. In Mac OS x has names but most only have telephone numbers. Also have multiple names for same contact as I tried to download again! I use an Apple IMac PC. Is there any easy way to remove all contacts and what is the best way to try again and get contacts to import with full information? I am not very Techy so plain English with any solution would be appreciated. Still have BT account and downloaded to a CSV file when trying.

A long-standing university email account that I accessed through Thunderbird was recently mistakenly deleted by the institutional administrator and all its contents deleted. The institution subsequently established a replacement email account for me, but the institutional Help Desk said the emails from the original account had been erased and could no longer be accessed from their server. Fortunately, I had Thunderbird configured to save all my emails on my local machine, so that even though I can no longer log in to the original email account, I can still view the emails in my Thunderbird installation (i.e., open and read them), even though every instance of starting up Thunderbird calls for me to supply the password for the original account (which I can no longer do). So I just close that dialogue box and can still see the emails stored locally on my machine.

I would like to move (or copy) these emails to a location where I can still access them off line and view them in the original organizational scheme (if possible), under the headings "subject," "correspondents," and "Date." But the Thunderbird "archive" feature seems to require that I be able to log on to the institutional server under the original account, which I can no longer do. The only existence of these emails is on my local computer.

Is there a way for me to preserve these emails as an accessible archive/repository so that I can continue having access to them, even though they are no longer in a functioning email account?

Thanks for any suggestions/help.

I had the situation maybe a year ago. I use the Firefox profile manager.

I just updated to 127.02, and now not I'm getting this because for whatever reason, since the update, I am somehow on the beta channel, but only with this profile. I just opened two other profiles, and neither is on the beta channel, although i don't know what "Firefox is being updated by another instance" means.

I don't know if it's just a coincidence, but I'm also just noticing that a number of my addons settings have reverted to default.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Hello,

I downloaded Google Takeout file, I was able to see it in my computer. But when I tried to import the mbox file into Thunderbird, it's not showing.

Note: For some reason, I cannot check the box below, requesting that I receive an email when someone answers the thread. Please email me when someone answers the thread.

Heya:)

I am a webdesigner and I'm currently designing a website for a client that uses Thunderbird for his mails.

Previously, Domain, website, and email had been hosted with the former agency.

Now we are gonna split this up into 3 different providers:

Webhosting: Squarespace Domain hosting: Cyon.ch E-Mail hosting: Would be great to keep using Thunderbird :)

How can I ensure that my client can still use Thunderbird? Do I just need to change some DNS-records? Otherwise I will have to switch to gmail :(

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?
