1. Often TB won't show new message, it'll list a number of new message, maybe I can actually scroll down & view a few of them, but quite often, I'll try to scroll down and can't see that new message that TB indicates exists. Or I have to click on an old message, then try again, click on another message I've already viewed then scroll down to where the new message is. This morning, tried both several times, still couldn't see the new message that TB insists is there.

2. At one time, when you opened TB, you were automatically taken to the end of all the messages in your inbox or if you fllter emails to folders, to the end of messages in that particular folder. No more, you have to scroll down to the end. Why? It's a waste of time for me to do that and as far as I know, TB places no limit on the number of emails in an inbox so . . . why was that changed? Because it was user friendly?

In my search I noticed that there was one TB user who was so upset he/she/they wanted to return to v. 102. I wonder how many people, seeing the response, also have returned to a previous version. I know I'm really tired of getting additional bells & whistles i don't use, changes to what you see that don't help me at all, plus making using TB more of a hassle--see above. Please fix the above problems. If it's not fixed in the next upgrade--which I'm hesitant to install given the result of the last few upgrades that introduced the above hassles--then I'll probably go back to an older version too.

I am using the current version of Thunderbird, I have been noticing for awhile now that changes I make to my profiles (adding new email accounts or changing smtp servers) are not being saved. In looking at my profile folder. I noticed several prefs-xx.js file but no prefs.js file. The last pref-xx file I have is from 2022 and it stopped at prefs-32. My question where did the prefs.js file go and how do I get it back.

Thanks Dan

When send a calendar event to an Attendee list I get an email notification if they've accepted or declined but I cannot see the status in the actual event. I also cannot manually update the attendee status. I should be able to see attendee status in the event shouldn't I?

Using Thunderbird 115.10.1 on Ubuntu

I am encountering a peculiar issue with the "Reply to All" functionality in Thunderbird, which I believe may be a bug or an unintended behavior within the application. I hope you can provide guidance or a solution.

Issue Description: When I attempt to "Reply to All" to an email that I previously sent (which is the last email in a conversation thread), Thunderbird automatically alters the sender's address. Specifically, instead of maintaining me as the sender, it changes the sender to the one (or the first one, if there's more) of the original recipients' addresses. As a result, the email appears as if it's being sent by the recipient back to themselves. This messes with the recipient's folders and rules, as the message has no indication it's been sent by me. This happens when I initiate the "Reply to All" action from the Sent folder on emails where I was the original sender. This only happens in one of the email accounts I'm using in Thunderbird, and it's a POP Mail Server type account.

Steps to Replicate:

Send an email to one or more recipients. Go to the Sent folder and open the email that was just sent. Click on "Reply to All." Notice that the sender's address is automatically changed to one of the recipients' (typically the first one, if there are more recipients). Expected Behavior: The sender's address should remain as my email address, not change to a recipient's address, ensuring the email is correctly identified as being sent by me to the other recipients.

Troubleshooting Steps Already Taken:

Verified that no extensions or add-ons are causing this behavior. Checked for any relevant settings within Thunderbird that could influence this behavior but found none. Updated Thunderbird to the latest version available. I would appreciate any advice, solutions, or workarounds you can offer to prevent Thunderbird from automatically changing the sender's address in this scenario. Please let me know if there are any logs or additional information I can provide to assist in resolving this issue.

Collecting mail one day, I received a Thunderbird message 'compact now'. After the compact process, some mailboxes are missing. How do I re-instate these deleted mailboxes?

hi all guys ... I'm experiencing several issues with oauth2 authentication, and I never had any issue before February the 2024 ... at the beginning the only account I have was not working was a microsoft account, so I thought it was "because of microsoft restriction"

but now, little by little, all my accounts requiring oauth2 authentication are failing, and I don't know were to check ...

I do NOT have any httpd/apache server running on localhost

I already tried changing things like general.useragent.compatMode.firefox or network.protocol-handler.warn-external.http network.protocol-handler.warn-external.https

I also created another blank profile ... but again ... not way to make it works ...

cookies are permitted ... javascript is enabled ...

the result is always the same ... a blank page when I try to do any oauth2 authentication ...

if I manually copy/paste that link in Firefox/Chrome it perfectly works, so it's not a network connection issue ...

from what I can understand, it seems to be related to the "built-in browser" in thunderbird, that for some reason does not work "as expected" ... If I try to click on any link for example in the settings page

like the "learn more" link of this option Send web sites a “Do Not Track” signal that you don’t want to be tracked "learn more" thunderbird does NOT show anything ...

something is broken, and I can NOT understand what it is ...

is there anyone with some good advices?

please let me know

thanks in advance

Stefano

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie

I am having older Thunderbird 102.13.1 and when i input into a search field for example: 37.19.223. or "37.19.223." or "37\.19\.223\." it always stupidly and uselessly output tons of messages that contains unrelated IPs:

([76.223.177. [10.223.144.96]

highlighting number 223 as if i have searched just for this number 223

I think that it is reasonable to expect from TB to output only search results where email contains 37.19.223. without any hack, escaping or regex or whatever (if you know a workaround, please kindly share it).

Maybe newer TB works better? Anyone tried? If it works same way, can you please kindly ask developers to fix this?

Here's the technical details: Win 10 Home 22H2 Build 19045.4291, Mozilla TB Thunderbird Version 78.4.0 Build ID 20201019003438 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828

This AM I was able to check / get e-mail five (5) or more times. Then clicking 'Get Mail' displays; connecting to mail.duo-county.com After 15-20 seconds connection to server mail.duo-county.com; Timed Out

I know of NO changes to any setting. When our e-mail was set up, we were told to set we were told to use Pop-3. Our ISP, who does NOT use NOR 'know' TB said we should be using IMAP, could NOT help review nor doing anything without risking ALL folders - files-data!

PLEASE help ASAP. Since we can't get - check mail I'm LOST! My spouse's e-mail is wpj@duo-county.com

Hello people of Firefox,

I'm attempting to deploy Mozilla to our android devices using MDM but need to be able to use our organization's Certificates.

I know I can manually go into the secret menu and set it to use third party CAs and that works but when deploying to over 500 devices that's not feasible...

Is there any configuration keys I can access to be able to remotely configure the application to use third-party CAs? (These are normally referred to as key-value pair)

Thanks.

For a few weeks I have had a new problem on my new Windows 11 Lenovo laptop, and also on my wife's older Dell laptop. We have been using Thunderbird for years without major problems. I loaded the latest version of Thunderbird on my new laptop and it seemed to work ok at first. Now I have a problem with intermittent failure to send normal emails on Thunderbird. My wife has noticed the same problem on her laptop Windows 11. I asked iPrimus support (who are supposed to support Hotkey) but they say it is not their problem but Thunderbird's. We RECEIVE emails ok, and sometimes pressing SEND will work immediately, sometimes on the second press, and sometimes not at all. This generates a message "-- Unable to authenticate Outgoing Server (SMTP), smtp.hotkey.net.au -- Check password and verify authentification method in Account settings/Outgoing server SMTP" We both use Trend virus protection.

Account name: mail.hotkey.net.au Outgoing Server: smtp.hotkey.net.au Server Settings: Server name pop.hotkey.net.au

                             User name is my email address

Hi I wish to have Firefox 125.0.2 and 124.02 'separate instances', not different profiles...

I already have 125.0.2 installed with various Profiles.

I found a 'few' links and they were quite 'cloudy' and also since Firefox (now) does not have the 'ask you WHERE to' install... I vaguely remember years ago, it was possible.

I do not mid doing tweaking, I also already have backups of profiles, just in case!

Thank you in advance M

PS it seems Mozilla does not want us to install multiple instances (perception)!

Question: How I can access shared folders in Thunderbird?

Office 365 business. I can access admin portal etc:

portal.office.com/adminportal

And also I can go to Exchange admin portal via this. So, in my opinion I can use all deep settings also.

Office 365 licenses (full) for name.lastname@company.fi. Portal show "Office 365 business standard".

I create also shared folders. Today shared folders found from "Teams groups". Log in to portal.office.com/adminportal, "Teams-Groups", and then "Shared mailboxes".

My conf: Office 365 business standard found name.lastname@company.fi. ("john.smith@company.fi", "alice.brown@company.fi" as example.)

Shared mailboxes sharebox1, sharebox2, so, it is possible receive email sharebox1@company.fi, sharebox2@company.fi etc. (in real life share box names are bookkeeperteam@company.fi, orders@company.fi, helpdesk@company.fi etc etc.)

CONFIGURATION IS FULLY WORKING. It is, in Outlook it is possible receive and send emails, shared folders with messages are available etc.

------ 

HOW I can add shared folders to Thunderbird? Clean install tested.

1. LIcenced mailboxes work properly in Thunderbird. Tested.

name.lastname@company.fi:

Server: outlook.office365.com, port 993 Username: name.lastname@company.fi Connection security: SSL/TSL Auth: OAuth2

And smtp: smtp.office365.com, 587, starttls, oauth, name.lastname@company.fi.

This configuration work properly, and it is possible receive and send email from Thunderbird.

SHARED FOLDERS

It is not possible add shared folders.

Server: outlook.office365.com, 993 Username: name.lastname@company.fi/sharebox1 (where name.lastname is real working account name, just same as in position 1- working account. Also this sharebox1 work in outlook.) Connection security: SSL/TSL (no difference is it this or stattsl) Auth: OAuth2

(I am sorry, all my systems are native language, so I must translate---)

OK: Now I try use this shared folder. It is visible in Thunderbird. But immediately thunderbird open Browser and ask password: "name.lastname/sharebox1", wrtite password. Now I put same pw as in this account (name.lastname..). "Password wrong." I try empty password. I try account password.

SO: HOW to add shared mailbox in Thunderbird? This information "name.lastname/sharebox" not work. Is it any other method? Or any Exchange setting modification make this?
