Thunderbird supportforum

I've been using TB for years with an AT&T account on a Windows 10 desktop. Two days ago all was working well sending and receiving. I stepped away for an hour (without obvious updates or changes) and surprisingly it didn't work, with TB asking for a password but not accepting it. I deleted saved passwords and tried multiple times, even changing my AT&T email password twice. I could access the email account directly through the AT&T website using those passwords.

I spoke with an AT&T support rep and he had me delete the account in TB. I did so but now can't reestablish it. I've repeatedly tried to add a new email account using credentials I know are correct, trying numerous POP3 and IMAP protocols, all without success. When TB probes the AT&T servers it says it finds those parameters, but then when it checks the password it fails, simply giving the vague message "Unable to log in at server. Probably wrong configuration, username, or password."

I've spent two days researching this problem and trying proposed solutions such as disabling firewalls and anti-virus programs, clearing Windows and internet caches, deleting saved passwords, etc. I was able to set up the account using Outlook on this computer, and if this continues I'll unfortunately be forced to abandon TB and move to Outlook or similar as a substitute. Advice would be appreciated!

After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?

We are using three locations to send emails from this email address. One of the computers at one home, sometime in mid April, was put into a block of some kind for having a PUP (the best I can figure out, don't really understand this stuff.) We had the block removed and most emails are now going through from that one computer. The other computers never had a problem getting their emails to the recipients. The one computer that had trouble, now has Maleware Bytes and Adwcleaner installed, that's what we did to get out of email jail I guess.

The problem is, any of the people that we attempted to email during the week or so that our email was in jail, even though it is fixed, our emails to those people are not getting to them still. We have to use another email address to get them to receive from thunderbird sent from our one computer.

We are not super computer savvy as far as this behind the scenes computer technology goes and need help so that we can reach all our customers reliably. We did try to identify if we were still blacklisted and saw 1 hit but don't understand how to fix it now that we have the additional spyware type stuff added to our computer. Your assistance would be greatly appreciated.

Thank you

I had to change my Google account and therefore my Gmail password due to a reported security breach. I've successfully changed my password for Gmail on my iPhone and iPad but I can't on T'Bird.

I expected that when I opened T'Bird, I'd get an error message saying my password was invalid and then prompting me to enter the new password for my Gmail account. That's the way it used to work and it worked well.

Instead, I get some sort of useless error message about STAT (??) and my credentials are invalid. I get no prompt to enter the now changed password. I get no info as to WHAT credentials aren't valid.

So I opened the Password Manager, found the Gmail line, entered Show Passwords and then edit password. I entered the new password, double checked it and closed out the Password Manager. I get the same useless message about STAT. The old password was *not* the Gmail password.

I opened the Password Manager to find the password is entered correctly. Why is this simple operation so miserably difficult? The old method worked perfectly every time now this one won't at all.

How do I disable automatic translation of Thunderbird messages by Deep-L (or any other machine translator)? This morning I received an email from a family member, written in German. Underneath the original message was an automated translation into English by Deep-L. I didn´t ask for this translation. I speak German as a second language, as well as other languages, and I enjoy using my linguistic abilities. Furthermore, I don´t like my private messages being passed to a database without my permission. If I want a translation of a message, I´ll ask for it.

This is evidently a new, annoying feature. I had an email exchange in German with someone just a few weeks ago without this intervention. I have tried searching the settings tab on Thunderbird, but have not discovered anything about Translation settings (not under Language settings, as far as I can see).

How do I disable Thunderbird sending emails for unwanted translation? Thank you for your assistance.

Hello;

Using Thunderbird v115.10.1 (64-bit) on Windows 10 PRO.

Once a month or so, I need to send some emails from another application. Keep getting the warning about "Another application is attempting to send mail using your user profile" (image attached).

OK... a very good warning.

But... I don't want to have to click <OK> every time an email is sent.

So... I unchecked the checkbox.

Warning gone... works great.

Now... I want to re-enable that warning in case a rogue application tries to send an email.

Have looked, and looked, and looked under \Tools\Settings and \Tools\AccountSettings.

Can not find how to re-enable this (if it's there I am looking right at it and not seeing it).

Can anyone help?

Also used regedit to search the Windows registry, but could not find it.

Also... is there a way to change settings from a CLI (would be nice to disable this warning, send the emails, then re-enable is all programmatically.

TIA.

Bo...

In our company, we have recently updated Thunderbird from version 52.3.0 to 115.9.0. Now we have a problem with href links containing file URIs in our messages. We often receive file links pointing to files in our local intranet, which look like this: <a href="file://///intranet.local/dfs/output/movie.mp4" class="moz-txt-link-freetext" moz-do-not-send="true">movie.mp4</a> Up to Thunterbird version 98.0b3 it was possible to open these files by simply clicking the link. But since version 99.0b1 file links don't open any more. Instead, the error console displays the following message: Security Error: Content at mailbox:///C:/Users/username/AppData/Roaming/Thunderbird/Profiles/profilename/Mail/Local%20Folders/Inbox?number=12345 may not load or link to file://///intranet.local/dfs/output/movie.mp4. Fortunately, it is possible to open the link with "Open Link In Browser" from the context menu. But we would like to get rid of this extra click. I already followed the steps in this document: http://kb.mozillazine.org/Links_to_local_pages_do_not_work#Firefox_1.5.2C_Mozilla_1.8.2C_and_newer Interestingly, this document is older than the time, when our problem was introduced into Thunderbird. Consequently, when I follow these steps, file links still don't open in an external application. Instead, they open inside of Thunderbird which is not the desired effect. To put my question in a nutshell: How can I open file links by left-clicking on them, just the way they open, when I right-click on them and select "Open Link In Browser"?

Steps to reproduce: On a Windows computer create a new mail. Press Ctrl-K to insert a link. Enter the following path with username replaced by your windows logon name: file:///C:/Users/username/Documents Save and close the mail. Watch the mail in the drafts folder. Click the link. Nothing happens, but you can see a message in the error console. Right click the link and select "Open Link In Browser". This opens your windows explorer.

Any solution is welcome, even if it's potentially insecure, since our computers don't have any internet access and we can receive internal mail only.

As a longtime user and a regular subscriber to Mozilla, I can’t get access to Thunderbird. Reason is that I had to repair the hard drive and now I am locked out. I am unable to insert a master password because I never had one. Reason being that I have used Thunderbird for years and years before that was required. To say I am frustrated is an understatement. None of your automated advice has a remedy. Should I install a new version of Thunderbird and begin afresh? John Cotterell ( an Australian supporter of your project)

April 15, 2024 Thunderbird is Insecure There is missing functionality issues

1. How to Disable the "SHOW PASSWORD" Button in Security Settings 2. Either implement with a Password Password option, only to show the Passwords or 3. Allow the ability to Disable the Button

back in 1916-18 the ability to disable the "SHOW PASSWORD" Button worked with with a variation of the following at that time user_pref("pref.privacy.disable_button.view_passwords", true); I believe I created and used chrome.css or chrome.js

At some point this functionality ceased to work.

Now, I have scoured the Net to figure out a Solution simply setting the value to True, gets reset by Thunderbird, TB does not save it. it always reverts back to False and the button remains available and does not disable

I have tried everything, adding it in user.js, settings.js, userChrome.js I put it in every directory, nothing seems to work

Do I have to Lock it? - How? confusing and disappointing.

Please provide a simple step by step Solution to the problem

Thank you

i have been away from my pc for 6 weeks and cannot access thunderbird. it repeated states that the login server IMAP.telstra.com failed my email hillsec@bigpond.net.au i have tried changing the in server and outgoing server to match my ipad and iphone which can receive emails. please help me to restore everything in thunderbird.

Without notice, Thunderbird today required me to sign-in to my Google account and then produced a window in which it said it wanted to access to my mail, contacts and calendar; in order to compose, send, share, delete permanently, among actions on my personal content. I tried to "Deny" (see below) but the window just returned and returned and could not be deleted. (see "Uploaded images", below for the content of this window).

Is this a scam? Or the result of a hacker?

Hello.

For some reason I haven't been able to figure, thunderbird keeps showing me the wrong certificate. I have an account with the server name "mail.estesc.ipc.pt" but when fetching email, thunderbird shows me a certificate for "cl.estesc.ipc.pt", does any one know why this happens or how to fix it?

Thanks.

Why is it impossible for Thunderbird to have an option to display the real senders email address instead of just the "fake" display and return address?

I use an addon to add the true address column in version 102, but as usual Mozilla upates disable useful security related updates.

When is Thunderbird going to show this essential true address instead of spending so much time changing the look and feel?

I am stuck with version 102 or another email client until this changes.
