Dear Thunderbird Development Team

I'm a regular Thunderbird user. I'd like to provide feedback regarding security concerns regarding the UI specifications of the Android version of Thunderbird.

Currently, Thunderbird for Android displays the sender's "display name only" on the email list screen, making the sender's actual email address invisible at all times.

I feel this specification increases the following risks, particularly in smartphone environments:

- Anyone can freely forge display names. - Phishing scams posing as financial institutions, e-commerce sites, and official support are common. - Users often rely on the list screen or notifications to determine the content of emails.

As a result, a UI that makes it difficult to determine whether an email is from a legitimate sender at the list screen level can become a breeding ground for phishing scams.

The PC version of Thunderbird allows for detailed header display, etc., and I'm disappointed that the mobile version of Thunderbird, despite being the same Thunderbird, is at a disadvantage in terms of security.

I would appreciate it if you could consider the following improvements.

- Setting to always display "display name + email address" on the email list screen

I am using Thunderbird with both Microsoft and Gmail accounts. My question is... is Microsoft able to see that i am using a Gmail account, and/or the account name/adress, and vise versa?

Hello. I know how to define a server certificate exception to avoid browser warnings in case of certificate issue with a website (see attachment). However, I'd like to apply that exception for all users with access to my machine using a GPO (for user or local machine). This is also a requirement in my work where many users run Firefox from a server and the face browser warnings all the time (related to self-signed certificates) so it would be great to apply an exception for all users through a GPO specifying the self-signed certificate warning we want Firefox to ignore. Thanks.

Hello,

I process phishing URL's,

I have recently come across URL's that make use of a BLOB: syntax on the URL:

blob:https://bolig.botik.dk/16c8c011-0fa5-4ba0-a10f-ed7675055cc6

You can see an example of the Phishing URL in this PhishTank entry:

https://phishtank.com/phish_detail.php?phish_id=9118779

That URL then re-directs to the above "BLOB" URL.

My understanding is that it is "locally" generating the phishing website, similar to an old fashioned about: syntax, however it's not clear what the significance of bolig.botik.dk URL is - loading that URL without the BLOB: prefix causes an error

Can someone explain:

1) What is the BLOB: syntax, and 2) what would be reported to have the phishing URL removed in the above example?

Hello, I've come across a rather strange problem. I have a phplist mailing list (on domain1). When sending emails, I usually also add an image (as a link to the image). Since the beginning of June, however, I've noticed that Thunderbird doesn't display the images added in this way. Instead of the image, it displays an empty frame (a completely empty frame without any tags). Even if "Allow remote content in messages" is checked in the settings. Other email clients (outlook, gmail, roundcube) have no problems and display images without any problems. However, if I put the image on another domain (domain2) and put a link to this image in the email, Thunderbird also displays it. So: it doesn't display the image from domain1, where I have the mailing list, but it displays the same image from domain2 (in the same email from the same mailing list from domain1). Is it possible that Thunderbird is blocking the display of images from a certain domain?

Recently asked by Mozilla Thunderbird for access to my data etc and this was questioned by Google. However I agreed to the request and wish to be assured that this was not a scam

Yesterday there was a 4 hour outage at AOL. I use Thunderbird to access my AOL account. When I discovered the outage, I check my Windows 10 hard drive where my Thunderbird emails are stored and it was empty. Not only was my INBOX empty but every saved folder, delete folder, trash folder, etc. Once AOL was operational, all of my emails reappeared on my hard drive. Everything appears to have been recovered without me doing anything. My question is: who has the ability to delete files from my hard drive without me specifically doing so either manually or through the Thunderbird app?

Dear Sirs, I got a letter about a donation to support Thunderbird and I payed 200 SEK. I was connected to https://updates.thunderbird.net/sv-SE/thunderbird/128.0/nov24/

Is it OK? Or did I a mistake?

When I attempt to add a Gmail account, I get this error - "Unable to login at server. Probably wrong configuration, username, or password"

Below are the steps with screenshots: - checked for no cookies to prevent Google from asking for an actual login - no stored google passwords - didn't put in my password on setup - TB finds the available configuration - prompted to login at google - add google password - allow access - error message

I have restarted Thunderbird. I have checked for updates (even though I have it on auto-update).

Are there settings on my Google or Gmail account that could prevent this from working?

I continually get popups wanting me to give permission for TBird to access all sorts of stuff. Is this a BUG or a "Feature"?. How do I turn them off? Or should I give permissions?

This is not the first time you have sent an email to me indicating I should "View all sites where your info is exposed", and each time I receive your emails the sites you suggest are sites I have never seen before, let alone logged into with a password.

I use a Password Organizer Book, with all of my logins and passwords for each site I use. I do not use a password app, and have NEVER used a password app. Each time I go to the website you suggest, It's always a site I have never seen before so it would be impossible to login and change the password. I always check my Password Organizer Book to make sure.

I don't know what you want me to do since I cannot login to the website you are suggesting. Is there action I should be taking? I don't know what it would be, but if you know please let me know.

Recently, some automatic updates were made to my Dell desktop. I assume they were updates to the Windows 11 OS.

The updates also caused some changes to my Thunderbird e-mails. The incoming e-mails are formatted differently. I used to get a message, saying that "remote content" in some incoming e-mails had been blocked. I was given the option to show remote content in the incoming e-mail. Now, I no longer have the option to "show remote content".

Please tell me how I can recover the option to "show remote content" on incoming e-mails.

Thank you.
