How do I change the font size of a Thunderbird thread list on a Mac?
I don't see any settings in the preferences.

Daniel's answer is correct. You have to extend userChrome.css
. Here is the CSS code that will fix the spacing as well:
/* Set default namespace to XUL */
@namespace
url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
/* Set font size in folder pane */
#folderTree >treechildren::-moz-tree-cell-text {
font-size: 12pt !important;
}
/* Set font size in thread pane */
#threadTree >treechildren::-moz-tree-cell-text {
font-size: 12pt !important;
}
/* Set height for cells in folder pane */
#folderTree >treechildren::-moz-tree-row {
height: 25px !important;
}
/* Set height for cells in thread pane */
#threadTree >treechildren::-moz-tree-row {
height: 25px !important;
}

You need to edit your userChrome.css file.
Go to ~/Library/Thunderbird/Profiles/[yourProfileName]/chrome/
(creating the chrome
directory if it doesn't exist) and edit userChrome.css
, again creating if it doesn't exist.
For example, to edit all text in Thunderbird (except message view), enter the following:
/* Global UI font */
*
{
font-size: 18pt !important;
font-family: Verdana !important;
}
The result looks something like this:
Unfortunately, I was unable to find the CSS class for the message list. Replace the *
in the CSS content with that CSS class, and it should work as intended.
Alternatively, let Thunderbird open the profile folder. In some versions, menu Help → Troubleshooting Information → Open Directory (near "Profile Directory"). – Peter Mortensen – 2020-01-04T00:14:01.970
Yes, this example is exaggerated, but how else can I prove it works? – Daniel Beck – 2011-01-26T18:30:57.627
This solution only helps a little bit, because you only increase the font - but you need to add space for that larger font as well. – None – 2012-05-31T13:43:04.790

You have to make a folder named chrome
in the profile folder. On a Mac it is located in /users/NAMEOFTHEUSER/Libraries/Thunderbird/Profiles/NAMEOFTHEPROFILE/
and there you need to make a new text file named userChrome.css
, as discussed in the previous answers.
listitem, treechildren::-moz-tree-row {
min-height: 2em !important;
}
2Can you expand your answer to explain where the user is meant to enter this code and what it will do? – Burgi – 2016-03-17T15:03:07.443
You have to make a folder named "chrome" in the profile folder. On a Mac it is located in /users/NAMEOFTHEUSER/Libraries/Thunderbird/Profiles/NAMEOFTHEPROFILE/ and there You need to make a new text file named userChrome.css. Just like the previous answers told – Nikola Kołodziejczyk – 2016-03-18T17:59:33.703
I suggest you have a read of How to write a good answer. It will explain how SuperUser works and hopefully in future prevent you from having answers deleted or from receiving downvotes.

I use the "Theme Font & Size Changer" add-on: https://addons.mozilla.org/de/thunderbird/addon/theme-font-size-changer/
This add-on gives you a little GUI, where you can easily change the font-size of the thread-list (and the tree), without fiddling around in the css file.
Please read How do I recommend software for some tips as to how you should go about recommending software. At the very least you should provide more than just/at least a link, for example some additional information about the software itself, and how it can be used to solve the problem in the question.
