I would like to know what the options below, contained in the settings editor, are for and how I can adjust them so that every message sent is configured to require confirmation of receipt by default:

mail.identity.default.request_receipt_header_type mail.identity.default.request_return_receipt_on mail.incorporate.return_receipt mail.receipt.request_header_type mail.receipt.request_return_receipt_on mail.request.return_receipt mail.server.default.incorporate_return_receipt

I would like to customize styling for recurring events in Calendar (115.11.1 on MacOS) without using extensions/add-ons. I enabled userChrome.css (`toolkit.legacyUserProfileCustomizations.stylesheets`) and the “has:” selector (`layout.css.has-selector.enabled`). In my userChrome.css, I added styles:

   li:has([alt*="Recurring"]) { background-color:grey !important; padding:1rem !important; }
   li:has(*[alt*="Recurring"]) { background-color:yellow !important; padding:1rem !important; }

Unfortunately, this seems to have no effect upon restarting Thunderbird. However, when I open Developer Toolbox (`Tools > Developer Toolbox > Developer Toolbox > Inspector` tab) suddenly everything works and the stylesheets are applied, but only until Thunderbird is shut down. Weirdly, other custom styles in userChrome.css work ok.

Is this intended behavior or a bug?

Basically, when I have a threaded message, I don't see the > to drop down information to show the threads from the subject pane in the subject field.

I have gone to view, sort by threaded. I'm led to believe I should see something like this:

Subject : Top Level of Thread

 |
 ---> Subject : Re: Top Level of Thread
      |
      ---> Subect : Re: Top Level of Thread

But I see none of that. It's just one flat subject. It doesn't even tell me someone has replied to me. I have to go into the mail to see that. I have added the conversations add on just to get a glance of that, because I'm seeing nothing.

Image attached of what I see.

I have stayed on an old version of TB because of the old extensions that made it a much better product.

With the installation of Win 11 I decided to try the latest version of TB. I have to say I am not impressed. I forgot how much better TB was with the extensions.

My first question is how do I get to sort the order of items I see in TB? I want News & Feeds to be displayed above my email accounts. It would seem that this would be easy but I cannot find a way of doing it. What am I not understanding? Surely this should be simple? I want to choose the order of everything.

I also customised the interface with better scrollbars etc. None of the add-ons I used to use seem to work with the latest TB. At the moment the new install of TB is incredibily ugly. How do I change that?

My company has a new name and I need to create a new signature. Now I have a problem: I have almost 200 email templates or drafts. The "old" signature is saved in these emails. I have created the new signature with the new name, but it doesn't seem to update automatically for emails in the templates or drafts folder.

Do you have an idea how I could solve this elegantly without having to edit all 200 mails manually?

Unfortunately, I couldn't find a "search and replace" command.

Many thanks for your help

I was able to change some of my message pane background by adding the following to the userContent.css file:

/* Thunderbird userContent.css */

@-moz-document url-prefix("imap:"),url-prefix("mailbox:"),url-prefix("news:") {

 body {
   background-color: #404552 !important;
 }

} @-moz-document url-prefix("about:blank?compose") {

 body {
   background-color: #404552 !important;
 }

}

I also tried adding the following to my userChrome.css file: /* Message pane */

1. msgHeaderView {

 background-color: #404552 !important;

}

1. messagePane {

 background-color: #404552 !important;

}

Why do I still get these two dark gray areas (see attached)? What css do I need to add to get them to be the lighter grey?

I am using Thunderbird 115.11.1 (32-bit) to manage 6 different email accounts for work and personal. I would like to be able to organize "Collected Addresses" according to the account they were used from.

Eg. I want each account to have it's own unique Collected Addresses address book Collected Addresses - Account 1 Collected Addresses - Account 2 Collected Addresses - Account 3 Collected Addresses - Account 4 Collected Addresses - Account 5 Collected Addresses - Account 6

I've looked online and there are some instructions, but they reference settings that I cannot find. Is there a way to do this?

TIA

I'm looking for a message filter function that will wait a specified period of time before performing what the rest of the filter does whatever it is tasked to do. For instance, I want to have an incoming message sit in the inbox until it moves to a local folder some time later. This would allow me to see it from a device that can't see local folders (like a mobile phone). I can't find anything in extensions. Any thoughts?

I have been using Thunderbird since the demise of Eudora. My configuration file is messed up and I would like to clean it up without losing everything. I have many accounts on different platforms. My unified inbox no longer works. It was working for my gmail accounts, but now nothing shows up in it. When looking through some accounts, there were multiple copies of emails in the archive file, and I never put them there.

Is there some way to preserve things like signature files and personalities and sever configurations, and set up thunderbird like a new install preserving the above and my contacts? It is a real mess now. I think there are multiple configuration files and I would like to delete some of them, but am afraid to.

我已经打开了“在需要时显示触摸键盘”选项，但是经过我的测试，所有的软件、浏览器（Chrome、edge、Steam等等）都能够正常唤起触摸键盘，只有Firefox不行

I have turned on the "Show a touch keyboard when necessary" option, but in my tests, all software and browsers (Chrome, edge, Steam, etc.) are able to call up the touch keyboard properly, except Firefox

I mistakenly moved a folder into another. It is now a subfolder and I want to move it back. The move command is not working. How do I move a subfolder back to be a primary folder?

Hi,

I do like how I can change the toolbar buttons that Thunderbird shows when I open Thunderbird. That is, I other mouse button click on the toolbar and select "Customize." I have a panoply of buttons to choose from, to arrange as I wish on the toolbar.

But, when I am reading an email, the buttons I see on the top left of the email window are: "Reply, Forward, Archive, Junk, Delete, More" (in Settings, I have "'Open messages' set to 'in a new message window'."

I have not been able to find a similar "Customize" ability for the toolbar of the message window.

Is there such an ability?

The reason I ask... I'd like to have similar control over that toolbar to that I have on the other Thunderbird toolbars. But I cannot find the appropriate Customize option.

What am I missing?

thx.

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

I have lost recent activity on home screen. There are blank tiles but nothing is being added.Hovering over tiles nothing happens. How do I get recent activity to appear again ?

To open a link of a website in the background tab is CTRL+click, why is it that to open a bookmark of the bookmark toolbar in the background tab is CTRL+shift+click. It is confusing! A bookmark is a link! For comparison, both of them are CTRL + click in chromium. BTW, there is no explanation in advanced configuration preferences.

This is something I've never encountered, since I hardly ever go to the Sent folder except to look at something I sent. But this was a different task.

I've had a series of emails from a friend, that my wife wanted me to forward to her so she could see them. So I went to the Sent folder, and forwarded 3 of those emails to my wife. Then she told me she only got one so I went back to Sent and thought they would be at the top of the list, 1-2-3, but that was not what I found. Since those emails were each part of several different threads in the back and forth with my friend, it took me a long time to figure out which email to pick off and resend. I made sure I was sorting them by date, descending, but was bewildered that the listing had the ones I wanted embedded (see screenshot, with the ones I just sent highlighted in red)

So my question is, is there a setting where I could tell Tbird to sort strictly by send date?

Hi there,

I'm having some difficulty getting my email signature for my new job set up correctly.

I want the company logo to appear on the left, with my details to the right of the logo, as seen in the first screenshot.

However, currently, the text appears incorrectly underneath the company logo. I have tried pasting the signature into a blank email, generating the HTML code and pasting that into the signature text box, yet it still displays incorrectly when sending an email.

The HTML for my email signature is as follows:

<tr>

 <td style="width:141.5pt;padding:0cm 5.4pt 0cm 5.4pt" width="189"
   valign="top">

 </td>
 <td style="width:6.0cm;padding:0cm 5.4pt 0cm 5.4pt" width="227"
   valign="top">
