Thunderbird: форум сообщества

If I mark a message as Unread, it appears in the list of messages in boldface type. But I am finding it very hard to distinguish those in bold from other messages that have been read and are not bold. Is there anything in advanced settings that would allow me to change the fill colour in the listing box, or perhaps the colour of the type, in order to distinguish unread messages more visibly from those I have read? Thanks!

I would like to see the sender's email address in lieu of a name.

The inbox SELECT COLUMNS TO DISPLAY does not offer an option to DISPLAY THE SENDER’S EMAIL ADDRESS.

Both From and Correspondents display the same names. Perhaps replacing one of those with the SENDER’S EMAIL ADDRESS?

The inbox font in the Thunderbird email client on my Mac is super tiny, and it's very hard to read. I can't figure out how to make it larger. Is there a way to do this? I really like Thunderbird so far, but if I can't read it, I can't use it.

Thanks! Mark

Taskbar icon does not indicate when new mail has arrived. Does not show a count of new/unread messages. 128.3.2 Windows 11

In settings "incoming mail" icon options I have chosen "show count of new emails" and "show a tray icon for unread messages is checked".

I am unable to tell at a glance if new email has arrived. I see from researching the KB I'm not the only to have this issue, but none of the settings seem to help.

When I select "Edit as New Message" in Thunderbird (v52.9.1) on a Mac, the message editor comes up in html mode even if I have set everything to plain text.

I have read all the articles on this and done all the things people have recommended including messing with Advanced options, account settings, etc. However, none of these solutions work.

Attached is a screenshot showing the problem. The first screenshot shows my inbox. The second shot shows that "Edit as new message" comes up in html mode.

Please advise.

Hello, I have enabled the Thunderbird dark mode. My expectation was that all messages in the message list are displayed in white on a dark background.

Unfortunately, the message list often uses a black font on a dark background.

I changed the color in the message pane using settings --> Colour

I followed the instructions/workarounds here for using dark theme, including reset and troubleshoot mode. https://support.mozilla.org/sv/questions/1439922

But it did not help. Maybe you guys can help.

Regards George

Presently I have minimize Thunderbird to tray icon set, this is fine. But I want Thunderbird to minimize to tray icon when I click the 'X' instead of closing out altogether. Since there's no setting for this, is there some kind of secret sauce like an add-on or a manual mod of the registry to enable this?

Many thanks.

Before the last update, when you assigned a colored label to the message (e.g., work, important, etc.), the entire title, header of the message, took the chosen color. Now you only see a small tag.

'The previous system was definitely more practical. Can it be reactivated?

Hi,

I have just started using Thunderbird and I'm trying to change the default colour for a hyperlink.

I have tried about:config -> browser.anchor_color and browser.active_color but neither has worked.

I also tried using a user.js file but that didn't work either.

I would have thought this would be a fairly basic thing but it seems to be impossible.

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

Hi,

I installed thunderbird in a new computer via flatpak. The computer is running PopOS 22.04 and the current Thunderbird version is 128.0esr.

I don't know if this happened after the last update from 127 to 128 or was like this before, but on the compose window all the menus and buttons on the top row are completeley invisible, white on white (if I hover over them, then they are slightly visible). See the first 2 images.

The main window is OK and everything is readable (see 3rd image).

I don't know how to change these colors.

Any help will be appreciated.

Hi

In Thunderbird version 128, the table view displays the subject line with different font colors based on tags, as shown in the example below.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-07-30-07-16-08-b0bfa9.png

I’ve seen at Thunderbird's release notes that Thunderbird supports displaying different font colors based on tags in the card view, as shown in the example below.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-07-30-07-28-44-d4881a.png

However, in my card view, the subject is displayed in white font, and only the tag label is highlighted, as shown in the example below.

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-07-30-07-20-48-f841b4.png

I would like to know if the card view in 128.0.1esr (64-bit) on Windows 11 has the capability to display the subject line with different font colors based on tags. If it does, could you please advise on how to configure it?

Hi, I'm using Thunderbird version 140.0 on Windows 10 and trying to change the background of the message pane. I've tried:

1. messagepanebox {

   background-color: #e6f3ff !important; 

}

but it only changes the upper part and I can't find a way to target the whole flex container or the lower part. There is a forum response (titled Message preview pane background) that targets the message pane:

1. messagePane {

background-image: url("file:///C:/path to image/image.jpg") !important;}

and that fills the message pane when its blank at startup but it disappears when selecting a message from the list.

I can add the background-color statement to :root in Developer Tools and that only works for the current selected message. How can I change the background of the entire Message Pane - the upper and lower part that contains the contents of the message - for each message that is selected? Thanks, David

I'm running Thunderbird 128.2.0esr (64-bit) on a Windows 11 PC. I can't find any way to associate a *.log file with notepad, even though this is the my windows default.

• Other file types work fine
• But Notepad isn't in the list when I double-click the file and I have to browse for it every time.
• When setting the default for another file type, it said this could be changed in "Options". I have Settings, but not Options. Under Menu > Settings > General, it has "Files & Attachments". Under this there are 2 columns: Content Type and Action. The only thing listed is Portable Document Content (PDF) and no way to add anything.* Bulleted list item

I recently upgraded to Thunderbird 128.2.3esr, and I no longer have the zebra stripes that alternate between my messages.

The userChrome.css file that appears in my profile's chrome folder is:

/* Light green, high-contrast zebra stripes in message list */

1. threadTree treechildren::-moz-tree-row(odd) {

-moz-appearance: none !important; background-image: none !important; /* background-color:#99E02E !important;} */

  background-color:#EEFFBB !important;} 

/* background-color:#AED6F1 !important;} */

1. threadTree treechildren::-moz-tree-row(selected) {

background-color:#45A1FF !important;}

Is there a reason that this no longer works? Can it be modified to restore the zebra stripes? Or is there an alternative code that will restore functionality?

Thanks in advance!

How can I define a filter to display all my saved messages with attachments exceeding a certain size, e.g. attachments larger than 5 MB?

Many thanks for any hint. Peter

When I receive some special html formatted email e.g. from ticket system like Zendesk they look like this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-17-01-06-32-c4ca42.png

When I want to reply to the text stays at the blue colored background and the text would be hard to read and it looks ugly: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-17-01-06-37-c81e72.png

Unfortunately I can't change background color to blank or white in Tunderbird 139.0.2. In menu of reply window "Page colors and Background", "Use custom colors", "Background" I can set to #ffffff of course, click apply and ok, but that doesn't change it: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-17-01-06-42-eccbc8.png

I suppose it relies to the html formatting of the received email because on starting to write a complete new email it works. But that's very annoying that Thunderbird doesn't manage to change background colors on already formatted html body. Is this a bug or only poor source code and the programmer didn't have much motivation to write and robust code which could gather all html emails?

Could you check with this test email to test and reproduce? https://limewire.com/d/pqbEk#1idjNje6b2

Thanks a lot! I'd be very happy about your help.

Hi all,

I tried to change the appearance of thunderbird using a userChrome.css file.

• I am sure it is located in the correct profile folder and has the correct name userChrome.css
• The userChrome.css file is also visible in the style editor of the development tools and displays the correct contents if I edit the file.
• I am sure that the toolkit.legacyUserProfileCustomizations.stylesheets is set to true
• I restarted tb millions of times

The contents of my userChrome.css file are currently (but I also played with different content):

/* Change background color for read messages */ treechildren::-moz-tree-row(read) {

   background-color: #f1f715 !important;  
   color: #6564cf !important; 

}

In the style editor, if i try to change the color code in one of the lines, it gives the following error messages:

Error while calling actor 'stylesheets's method 'update' document is null Actor.js:103:13

   writeError resource://devtools/shared/protocol/Actor.js:103
   handler resource://devtools/shared/protocol/Actor.js:242

InvisibleToDebugger: TypeError { } Actor.js:110:15

   writeError resource://devtools/shared/protocol/Actor.js:110
   handler resource://devtools/shared/protocol/Actor.js:242

I am running thunderbird 128.3.1esr (64-bit) on mac sonoma 14.6.1 (23G93)

Does anybody know how to get the style sheet running?

Thanks, ulrike

I am using following userChrome.css modification for zebra stripes:

/* Message List colors */ /* Odd rows color */

1. threadTree tr .card-container {

 background-color: #27272a !important;

} /* Even rows color */

1. threadTree tr:nth-child(2n) .card-container {

 background-color: #2d3237 !important;

}

It partly works, but I miss default system color in background, there is only border line. Please see attached images.

Many thanks in advance!
