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.

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 wrote an email without putting in anyone for the 'TO:' or 'CC:' fields. The BCC: field only had my own email address in it.

I accidentally sent this email before I had sorted out the TO: and CC: fields properly.

In my sent email and it had 'undisclosed-recipients' in the To: field.

I found this disconcerting, since I wasn't SURE if I hadn't put anything in the CC: or TO: fields. I worried I may have sent a rough, poorly worded email to someone and that could backfilre.

Am I right that whenever 'undisclosed-recipients' is shown in the To: field and I sent the email, I can check in that sent email who was in the BCC: field and that should re-assure me who had actually recieved a copy of that email.

Clarity in this area would be VERY helpful.

My office is running Thunderbird 115. I recently changed the password. This seemed to work OK. But on restarting TB I found the new password had not been stored. The Password Manager display is empty, so I cannot edit anything, nor can I insert a new entry into the Manager. I want to store the current password. How do I do this?

I have spent the last TWO HOURS trying to find an answer to what should be a simple problem, and it seems not to exist!

I need to find out WHERE Firebird lists my email account PASSWORD.

I do NOT want to reset my password.

I simple need to know WHAT my password is, and since I set up the account [actually a few accounts] several years ago, my notes are evidently null and void, because none of those passwords seem to work.

My email is through verizon.net, which is one of the problems because they gave all of their email coltrol to AOL, which thouroughly sucks, and they seem not to have anyone who speaks fluent English who can assist me in FINDING the current password!

If ANYONE can help, it would be most greatly appreciated!!

I do not understand how to set Thunderbird for Comcast's two step passcode. How do I get the passcode, My bank sends a passcode by landline for checking and email for credit card.

Hello,

I am getting a failed mailed delivery message every time I send an email.

The error reads:

host submission.antispam.mailspamprotection.com [34.111.121.216] SMTP error from remote mail server after end of data; 550 high probability of spam 1rITD-006zLY-2v

Hi All,

Not really have no clue what's happening, I think I've by accident put some kind of rule on. It's only with one organization whenever they send me an email I see it coming in but in a blink of an eye it's gone. I've looked everywhere what could be the problem but can't find it. Even when I search on the subject in my inbox, Thunderbird shows me it found emails but doesn't show when any, only the count of the emails.

When I check the mails do stay in my web-based Outlook, via "Owl for Exchange" I get my mails in Thunderbird, no other emails have this problem.

Anyone who could point me in the right direction would be much appreciated.

Many thanks! ~Muriel

I use Thunderbird on my Windows 10 desktop PC to access multiple Gmail accounts.

Since March 22nd I have been unable to send or receive email on all of my Gmail accounts. This failure started on all of my Gmail accounts simultaneously. Initially I received a popup message in the lower right portion of my screen reporting authorization failure (sorry, but I do not have the exact text of this message).

Currently I receive the following message: "Did not connect: Potential Security Issue" "Thunderbird detected a potential security threat and did not continue to accounts.google.com because the website requires a secure connection." (I get one of these messages for each Gmail account).

My troubleshooting steps so far

1) I have verified all of my passwords via the Gmail web portal. Passwords function normally. 2) My Gmail email still functions normally on my tablet and my phone. 3) I have completely uninstalled (rebooted) then re-installed Thunderbird on my PC. Failure - same message as above. 4) I have removed one of my Gmail accounts (rebooted) then reinstalled the account. Both via the Thunderbird automated tool and via manual setup (following instructions supplied by both Mozilla and Google). Failure - same message as above. 5) I have installed a different email app (BlueMail) on my PC and set up my gmail accounts. All accounts function as expected. (BlueMail sucks but at least it's functional...LOL). 6) Through the course of my trouble shooting I did receive a one time Thunderbird message indicating that Gmails security certificate had expired. (Doubtful) 7) I am running a fairly basic home network with only Windows Defender providing a software security layer. 8) I have searched through this forum (and the internet at large) for possible solutions. While the error messages I have received seem reasonably common, none of the suggested solutions have proved beneficial. 9) While not impossible, I can not associate this issue with any changes I have made with my PC hardware or software.

After retiring from the corporate world I decided that Outlook had far more complexity than I needed, so after trying out numerous email applications (both free and paid) I settled on Thunderbird which has worked flawlessly for me for over 3 years. I am currently at my wits end... hopefully someone in this forum can help. Thanks in advance, Mark H.

I'm having trouble with my Thunderbird password. I have 2 emails with identical settings and passwords. One works fine. The other's asking me for my password. When I enter what I knew for certain was the password I get the message, "Login to server imap.comcast.net with username weissfamily@comcast.net failed." I successfully changed the password still get the same error message. Also I get a Thunderbird popup that says, "Alert from account weissfamily@comcast.net: 1014." This is all above my pay grade. Need assistance. TIA. Tim Weiss

Trying to add https://search.yahoo.com/search?p=%s&fr=opensearch

results in an error message:

Could not add OpenSearch Provider for https://search.yahoo.com/search?p=%s&fr=opensearch.

So what am I doing wrong.

Lately I have been getting a lot of spam and have identified all coming into my inbox as spam. Now many are automatically moved to junk mail box and that is a good thing. Unfortunately it also seems to be slowing Thunderbird down. I am afraid that many of the "Filters" generated may be duplicated. Is it possible to see them and maybe edit them to reduce the impact on my system?

Sorry in advance for the long reading.

For my personal needs I'm currently using the general purpose desktop platform UBUNTU 22.04.04 LTS and GNOME/WAYLAND. Thunderbird is my personal e-mail and productivity client application, now in it's stable version 115.8.1 (64 bits).

For many years I used to sign my personal emails using S/MIME and a high assurance (Qualified) X.509 digital certificate, protected by my personal ID card (i.e. a smartcard), which is provided by my government (Belgium). It used to work flawlessly under Xubuntu, my favorite OS flavor until about a year ago, with earlier versions of Thunderbird.

Since I migrated to UBUNTU's standard flavour (using WAYLAND), it doesn't work any longer.

I experienced the same behaviour with Firefox when Canonical started distributing only the SNAP version of the app for Ubuntu. This problem is well known and documented. I applied the recommended solution, which was - and still is - to install the Mozilla binary version along the snap version. I can since happily continue authenticating and connecting securely to any belgian e-government web site using the Mozilla firefox binary version with my certificates/Id card, while using the snap version for other purposes.

So I tried the same recipe with Thunderbird, ... to no avail. Both versions (Ubuntu-snap and Mozilla-binary version 115.8.1) display the same, consistent behaviour. I must precise here that I can load the BELPIC PKCS#11 subsytem and configure Thunderbird like I always did. After asking for my smartcard's PIN, TB can access the smartcard and lets me associate my certificate with my email account. Everything seems to work as usual until there, except that signing a message does not work. TB systematically displays the same error message "... the application does not find the certificate or the certificate has expired". Of course my certificate is not expired. It looks like the message composer (not Thunderbird itself) cannot access the smartcard. Disabling apparmor leads to the same result with both the snap and Mozilla versions of TB.

Still, TB - both versions - works as expected when using low-assurance digital certificates, e.g. issued by CAcert.org. I also use those for receiving encrypted personal messages when needed. But those are stored locally together with their private keys.

There is no interest in signing messages with a digital certificate without any legal value, especially on a system that is meant to be more secure. I migrated to the standard ubuntu desktop for the added security provided by snap, apparmor, Wayland, ...

Before I file in a bug record, would someone be in a position to provide any useful hint?

Many thanks in advance.
