Thunderbird has worked great for a couple of years. Recently, I kept getting the “Retry” prompt...sometimes two or three times before it would download my email from the server (windstream.net). Now I get nothing. It still goes through the "connecting...blah blah blah but nothing happens. Going to the windstream.net site works but sucks. Any help or suggestions would be greatly appreciated.

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.

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?

When using backspace during editing, cursor position jumps to wrong spot

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.).
