Help needed changing font size of infox column headings

[tomdkat]

Hi! I've managed to increase the font size of just about everything in Thunderbird *except* the columns headings that appear in the inbox (e.g. "Subject", "Date", "From", etc). Does anyone know how to change the font size of the column headings? This is in Thunderbird 91.9.1 on Ubuntu Linux.

Thanks in advance!

Peace...

Try this:

Code: Select all

/* Thunderbird userChrome.css */

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#threadTree > treecols > treecol {
  font-size: 15px !important;
  color: orange !important; /* test */
}

Remember to set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true, then restart.

Hello Morat,
I tried your suggestion. Color worked. Font-size didn't. Tried 15px and 15pt, and other sizes.
Added (for the heck of it) text-decoration: underline wavy red 5px !important;
It worked OK.

Some users may not notice the different between the default font size and 15px. Try 8px instead of 15px.

It works for me. Maybe an addon is overriding the entry.

Tried 8px then got a bit radical and tried 30px. No difference.
Oh well, we tried.
Thanks for the reply.

Thanks for posting this! It worked perfectly!!!!

So, what I did was specify a font size of "2em" instead of using pixels or points. Once I restarted Thunderbird, the column headings were huge. I then adjusted the size down to 1.5em and changed the color to red. I also added some padding to create some separation between the column headings and the column data.

I don't know if using "em" made a difference for me, but it certainly did work.

I tried px, pt and em without success.
Searched for any conflicting entries in my CSS and found nothing.
Just not my day.

You've confirmed the 'toolkit.legacyUserProfileCustomizations.stylesheets' setting is set to "True" in the advanced configuration settings, right?

Yup, toolkit.legacy.... is set to true.
I've got some extensive tweaks in my CSS and they all work as expected.
Update:
Found the issue. The following code is at the beginning of my CSS.
Apparently this has precedence over any following code.
/*
*Make all the default font sizes eg:14 px:
*/

* {
/* Affects icon toolbar, quickfolders, etc */
font-size: 14px !important;
/*font-style: italic !important;*/
font-family: Bahnschrift, Georgia, Arial, Geneva, Helvetica, sans-serif !important;
}
