I’m running Thunderbird 147.0.1 (64-bit) on both my desktop and laptop, both using Windows 11 Version 25H2 (Build 26200.7705). I’m trying to highlight sent (outgoing) messages where the correspondent and recipient are different (i.e., not sending to myself). When this condition is met, I want the subject line to appear green. My logic is: • Match outgoing mail where the correspondent column contains one of my addresses • Exclude rows where the recipient column also contains one of my addresses • Apply formatting only to the subject column tr:has(

   td.correspondentcol-column[title*="@pm.me"],
   td.correspondentcol-column[title*="@protonmail.com"],
   td.correspondentcol-column[title*="@passinbox.com"]

):not(

   :has(td.recipientcol-column[title*="@pm.me"]),
   :has(td.recipientcol-column[title*="@protonmail.com"]),
   :has(td.recipientcol-column[title*="@passinbox.com"])

) td.subjectcol-column {

 color: var(--tb-green) !important;
 font-weight: 600 !important;
 background-color: #e8f5e9 !important;

} Same Thunderbird version, same Windows build, same CSS file, same mail account structure. Is there something on the desktop system that could prevent this from working? For example: • about:config setting related to CSS • Layout or column differences affecting selectors • Rendering engine differences between installations • UI density / table layout mode differences My expectation is that this logic should behave identically on both systems, so I suspect a configuration or UI state difference. Any guidance would be appreciated.

The ability to select "Done" for New Contacts is totally off-screen on the right when using part-screen (screenshot2 below). When in full screen only a part of the box is available to complete and entry (screenshot1 below).

I've tried adjusting font size and other stuff in Windows 10, but nothing changed the way the Thunderbird looks in this regard.

I had Mozilla which I accidentally deleted a couple of years ago. Spectrum serviced my email, dmarsh38@roadrunner.com, since then but now has abruptly cut that off. I'm wondering if Thunderbird will resume servicing this email, and how do I make that happen, how do I access it, etc.? I'm trying to avoid having to change my email address of 30 years.

It recently came to my attention that Gmail is using my (and others) emails to train their AI to provide "overviews" for email threads. I didn't find that in any of the recent Agreement changes so feel safe is stating Alphabet/Google never obtained my permission for this training. I'm not a fan of the far-flung use of AI and the mounting examples of how horrendously Google AI performs hasn't done anything to relieve my concerns.

I began a search for a better, reliable email client and there is a depressing shortage of them that fulfill the average email users' needs. Thunderbird looks pretty good but reading through the Help section, Community Forum questions and just general articles hasn't clarified a couple of questions I have.

1. Is Thunderbird a comprehensive email client, independent of other clients, or does it provide service by partnering with another client?

2. Does Thunderbird utilize AI for any purpose that requires the "review" and storage of individual users' emails?

Many thanks, MarilynB

I have been using Tbird for years. I currently have 3 email accounts, an icloud and two gmail. One gmail account is personal, the other is a personal account but used by 3 people for a committee we're on. The first two accounts are ok but the committee account has lost most of its messages at gmail, but they still seem to be on my computer.

Despite having used T'bird for a long time I still need detailed instructions in how to proceed to put the messages back onto the gmail account, hopefully without touching the other two accounts

Continuation of my prior post: https://support.mozilla.org/en-US/questions/1516342

Thunderbird has a routine problem with being unable to log into various mail servers. I have four accounts and they all seem to share this problem.

Most recent update: I've tested this in Windows Safe Mode, and the problem has not appeared. Since I can't do any useful work in Safe Mode, it's hard to give it a thorough test, but so far so good. Also, I have removed AVG antivirus because it was redundant. I have seen no improvement since it was removed.

Can this problem be resolved?

The messages do not show in the email folders. it happened after I tried to delete some folders I didn't need. The folders have an icon next to them that lists the number of messages in the folder. When opened, most of the folders say "No message found."

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

No new emails appear to have been downloaded since 12.00 GMT on 27.01.26.

Size of file on disc suggests they are there but not displaying.

Downloads working fine on iPhone and iPad.

It seems to me that the account settings in Thunderbird 140.6.0esr (64-bit) have changed, because without any supporting documentation in 'help' I can no longer see a way to enter a password. I have two gmail accounts which are working but I also have a Protonmail account which has stopped working. The Protonmail Bridge show the following details for entry in the Thunderbird client's account settings:

IMAP: Hostname (127.0.0.1), Port(1143), Username(withheld), Password(withheld), Security (STARTTLS)

SMTP: Hostname (127.0.0.1), Port(1025), Username(withheld), Password(withheld), Security (STARTTLS)

I can enter the following: Hostname, (127.0.0.1), Port(1025), Username(withheld), Connection Security(STARTTLS) & Authentication method (normal password) but nowhere to enter the actual password!

How do I do this and where in the docs is this described, please Thanks

This has been happening for a long long time - probably a few years' worth of versions. I have just put up with it... currently running Tbird 147 and it just happened.

When editing an email (either the body or the Subject), if you use the backspace button (the one that deletes to the left) to delete some text sometimes the cursor will incorrectly be positioned about 5 or 6 characters further left than it should.

For example, if I had the text: "Quick brown fox jumps over the moon"

If I were to highlight "fox" in the above example, and hit backspace, I would expect the cursor to end up positioned between the remaining spaces after 'brown' ( pipe symbol here is meant to represent the cursor position): "brown | jumps"

But instead what happens is that the cursor ends up somewhere among/before the word "brown". It's always further left than it should be, by 5 or 6 characters.

I believe it only happens when highlighting multiple characters and then hitting backspace. It may be more (only?) prevalent when editing/replying to an existing email. (But I'm still only editing the new portions that I add at the top of the email; I'm almost never editing in amongst the original quoted email content.)

I also haven't ever been able to figure out how to make it happen, sorry. It is just random...It will happen once in an email, but then not again. But it happens frequently - 3-6 times a day perhaps. (Depends on how many emails I am editing.  :) )

I don't believe that I have noticed this issue if I were using the Delete button (deletes things to the right). I don't think it happens when backspacing one character at a time...but it might. I also use Option-Backspace to delete whole words at a time (instead of highlighting the word); not exactly sure if it happens only if highlighting a word, or only if Option-Backspace, or single key press... sorry, it is so random and unexpected that I don't have more specifics.

Bonjour, je pratique THUNDERBIRD depuis de très nombreuses années et j'en suis très satisfait. D'ailleurs j'ai contribué à des donations au cours de l'année précédente. Je viens de constater tout récemment plusieurs choses qui me gênent : 1) je ne vois plus apparaître la commande "insérer" pour insérer une image dans un texte 2) quand j'enregistre un message pour le sauvegarder je ne vois que le texte du message, mais plus les entêtes (adresses e-mail, date, etc.). Pouvez-vous me donner des explications s'il vous plaît ? Merci par avance. Guy ROBIN guyrobinggl@gmail.com

Hello, I have been using THUNDERBIRD for many years and I am very satisfied with it. In fact, I contributed to donations during the previous year. I have just recently noticed several things that bother me: 1) I no longer see the "insert" command appear to insert an image into a text 2) when I save a message to save it I only see the text of the message, but no longer the headers (e-mail addresses, date, etc.). Can you give me an explanation please? Thank you in advance. Guy ROBIN guyrobinggl@gmail.com

Hi Team My Thunderbird account has a font corruption. Whenever I open a new message, The font appears as a weird shadowy type - See image attached. The signature is saved image. I can't set a Tahoma or Verdana or any from the overall font list as the base font. However, when I send the email, the recipient sees a normal tahoma font. Help!

Cheers Ian A user for 20 years at least!

When using Thunderbird 140 I am able to setup the background color of the message pane for individual messages. However when the messages are threaded, the message pane shows a preview of all of the threaded messages together in the message pane with a different background color than individual messages.

I have a domain so any email I use comprises of name@mydomain.co.uk

In the past I have given an email address to some dodgy enterprises such as Abbey National plc, and so I get loads of spam to abbey@mydomain.co.uk

It is an utter pain that many spammers use a throw away or random To: address but because the envelope email is abbey@mydomain.co.uk I get to receive it and there is no easy way of searching a folder to find matches to "envelope to".

Similarly it seems impossible to construct filters for an "envelope to" address.

Any ideas?
