Running TB 128.12.0esr on Linux Mint. I can get striping in my Classic View thread pane with:

1. threadPane tr:nth-of-type(odd) {

 background-color: rgb(215,215,215) !important; 

}

But how can I achieve the same effect in the folder pane? I have tried replacing threadPane with folderPane or folderTree but no luck.

In Developer Toolbox the selector for the folder list appears to be is(ul, ol)[role="tree"] but I don't know how to create a striping rule from that.

New computer Ubuntu 24.04 Mate, older Ubuntu 22.04 Cinnamon. Following support transfer directions (open Thunderbird on new PC, close it, paste a copy of older .thunderbird from USB stick to .thunderbird on new, over write), when I open Thunderbird no accounts are shown only the create account screen. I find no update path for older Thunderbird. New PC came with 128 esr but I found a tarball of 115 .18.0, installed it and followed transfer directions with the same results. Seems like the esr version uses a profile ending with esr and ignores my older one. What are my options for transferring 20 years of significant messages? The hard way might be to identify the account specific files in my older profile and copy them into the new esr profile...

I am able to style tasks that are either completed/overdue/inprogress in userChrome.css . But so far I have not found a way to style canceled tasks.

Can someone help me ?

wen man in Thunderbird auf die Tabs klickt ("Betreff", "Beteiligte", "Datum", etc.) werden die Mails nach diesen "Kriterien sortiert"

kan man diese Funktion irgendwie sperren oder deaktivieren? Mich regt es immer auf wenn ich versehentrlich drauaf klicke das er die Sorterung ändert udn ich brauche diesen Murks nicht.

wie kan man das abschalten?

When I downloaded the Thunderbird app to my new laptop and opened it, it already had a fortnight's worth of recent messages in the Inbox, plus many of my Sent messages. However, the remainder of the Inbox, dating back to 2010, was not there, neither were my address books. Why didn't a clean copy of the app download so I can import my Profiles? In addition, my old laptop uses POP incoming, but the new laptop seems to be configured to IMAP. Is this a problem, and if so, which should I choose for the new laptop?

firstly, i'd like to say this isn't really about settings, well it sort of is, it's about layouts, but there's no heading for that. sorry!

i've just gone from version 102 to version 128. for my use of Thunderbird, nothing much seems to have changed, except some things are now harder. (such is progress!) i would like to see the columns in message lists as proper columns, with headers you can click on. so only one line per message, as it used to be, would suit me just fine. that way i can compare things in the list, which i would say is really important. you can change the sort, and easily see how it effects things.

does anyone know if is there any way to achieve this? i can't see anything in Settings or View. thanks so much.

Have just installed TB for the first time (replacing WLM) and am very happy with it. My only problem is that the option to open with a blank page is not working despite leaving the checkbox unchecked. I've tried checking and unchecking but it makes no difference, it always opens with the full setup options displayed. Is there another way to have TB open with a blank page?

Thunderbird doesn't natively show number icons for the number of emails in folders other than INBOX (maybe one or two others). I miss messages in other folders because they don't display emails present. How do I enable this for other mail folders? Checked interweb; didn't seem to apply.

I grew too used to the zebra striping pattern in my message list, but could not find a way of implementing it in Thunderbird settings. I'm using version 139.0.2 - aarch64.

I did try to use the code available in this forum, which involves creating a folder "chrome" in the user profile and then a file userChrome.css under it. I did turn on toolkit.legacyUserProfileCustomizations.stylesheets and understand this is not recommended, but it did not make any difference anyways.

Any pointer would be much appreciated.

when I click reply to an email the new message font size decreases (hard to read) and I can only type in the same size font as the original message and can find nowhere to increase font sizes etc

I am having some trouble getting Thunderbird to display all my messages. I tried troubleshooting mode and found that all the messages were displayed. Restarting in normal mode having disabled my extensions and hardware acceleration, the problem returned and I could not see most of my messages. So I need to make the other changes that troubleshooting mode makes. These are described at https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird as

• Window and sidebar size and position settings (described in terms of Firefox)
• userChrome and userContent customizations ; see userChrome.css and .js and userContent are unsupported

I do not understand what these are and how I can set them for routine use. Can someone point me to an explanation? Thanks.

As noted in my question something odd has appeared in my Thunderbird Email. Can someone help me get back to all English. I double checked my TB settings and it appears they are all set correctly.

Thanks, Brad

I've moved thunderbird between windows 10 computers several times without any issues in the past, but I'm having problems now.

My old PC is running windows 10 with the most up to date TB. New machine has windows 11.

In the past, it was just a case of installing TB on the new machine and replacing the profile folder there with the one from the old machine.

Now when I do this I get "your thunderbird profile could not be loaded. It may be missing or inaccessible"

Ay help with this woould be much appreciated

Hello there,

I am using Thunderbird 128.11.1esr on macOS Ventura 13.7.6 (OCLP) and would like to have all my accounts displayed in one unified inbox:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-16-23-42-32-0314df.png

In the past all my accounts relied on pop3, but now of them changed to imap only, which now shows up like this:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-16-23-43-14-1d6721.png

Is there a way for me to have just one inbox folder? I set it up like this ages ago but can't recall which steps need to be taken to receive the desired view.

If I choose View > Folders > Unified folders I get this:

Thanks in advance!

Transfer Thunderbird email and data to another computer. I have attempted to transfer my email data from / to Windows 10 computers. The instructions seem straightforward but so far I have not been able to bring up the "new" computer after copying / transferring the data. I have a Linux laptop I could transfer to, but the versions don't match and I'm not sure it would work anyway. Any help or direction to instructions (I thought I have looked everywhere) would be great. Thanks

I thought this problem was resolved last month. Today, all my historic emails have disappeared but are visible in safe/troubleshoot mode.

I have done the following:

1) Disabled all extensions. 2)Themes are set to default. 3) force updates through Help - "About" .

It seems that all new emails are being shown in TB but all historic ones have diappeared except for in safe mode.

Please could someon help. Thank you so much

I'm looking for solution to make or prevent Thunderbird automatically filling up the "From" box.

In other words; I want the "From" section to be empty every single time for me to fill up. Just like I have to do with the "Subject" and "to" boxes.

I'm willing to hack Thunderbird if there's no an user friendly solution for this I want! Just please tell me what to do and I'll do!

Thank you in advance, Attila.

I can't seem to get the search message window to shrink down with the right click commands, nor with the arrows at the edges of the window, this has been going on since the beginning of 128 . . .
