I just contributed to Thunderbird and and will contribute more if I can change the fonts used in the interface menus and toolbars. I am visually impaired and am unlikely to be able to see Thunderbird's menus at all a year from now. I tried creating a userChrome.css file but it has no effect so there must be something wrong with it. This is what I have:

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

* 
* change font for ALL UI elements  does not affect content
*/
  • {

font-size: 14pt !important;

 	font-family: "Arial Nova" !important; 
       font-weight: bold !important;
 } 

/*

*   Threads and folder panes   
  • /

.tree-rows {

 font-size: 14px !important;

}

/*

* Menu Bar font 

menubar > menu {

  font-size: 14pt !important;
   font-weight: bold !important;

}

  1. tabs-toolbar .tab-text {

font-size: 14pt !important; font-weight: bold !important; }

I got this code from a few examples I found. Any help getting this to work would be appreciated a great deal.

This approach makes fonts bigger, but not bolder: This is a general step that increases fonts somewhat. It may do what you wish. In tools>settings>general scroll to bottom where config editor is. the entry to change is layout.css.devPixelsPerPx the default is -1. Try maybe changing to 1 or 2 and see how that looks, but be careful if you set too high. I suggest 1.1 for a start.

This code enlarges the Menu Bar and submenu fonts, and makes them bold (see picture):

/* Menu Bar font */
menubar > menu
{ font-size: 18pt !important;
font-weight: bold !important;
}

/* Submenus and context menus font */
menupopup,popup {
    font-size: 12pt !important;
    font-weight: bold !important;
}

Changing the Mail Toolbar buttons is a bit more complex, but I suggest using the Phoenity Icons add-on as first step in making them more visible.

The change in pixels was great. With that I can even see the smaller text. I also enabled legacy using the Config Editor. I had found some examples for my userChrome.css but did not know that I needed to enable legacy to get it to work. Thanks much.
