  1. This article was written for Thunderbird but also applies to Mozilla Suite / SeaMonkey (though some menu sequences may differ). You can change the font, font size, and other attributes of fonts used in the folder pane, message-list pane, menus, and elsewhere in the user interface (UI).
  2. Those using Thunderbird and are bugged by fonts too small this easy font size and theme changer works very well indeed. (Works in Firefox browser too if you are using that) Theme Font Size Changer:: Add-ons for Firefox To install manually simply download and in Thunderbird / Firefox simply load add on from file and point to downloaded file.
  3. Select Thunderbird Preferences (Tools Options on a Windows computer) from the Thunderbird menu bar.
  4. Go to advanced preferences in Thunderbird and click on Config Editor. Find “font.size.systemFontScale” and adjust the scale (do so.gradually.! Try maybe 10-15 increase/decrease at a time until you get to where you want. Changes will show when you close the Mail window and reopen it (or restart Thunderbird).

Well, on Mac OS X there is no easy way to specify the size of system
fonts--at least, I couldn't find such a way. (The 'Universal Access'
preferences allow you to configure text zooming, but not to change the
size of the default fonts. This is on 10.4.7, incidentally.) Note that
Apple's native browser and email applications (Safari and Mail.app)
allow (require?) that font sizes be set directly in the application.

Thunderbird normally uses whatever font size Windows tells it to use. So the easiest way to change the size is to change it in your Windows settings. You can use a userChrome.css file to force the size to be different from your Windows settings. That is an unusual thing to do, so Thunderbird does not provide an easy way to do it.

Note also that it's possible that a person might want different size
fonts for different parts of the application. For example, Apple's
Mail.app email program allows you to specify font sizes for three types
of text independently: 'Mailbox font' (used to display the names of mail
folders), 'Message list font' (used to display message subject, sender,
etc., in the message list pane), and 'Message font' (used to display the
message body).

This is very handy, since a user would presumably put a higher priority
on reading the message itself than on reading the message list, and a
higher priority on reading the message list than reading the folder
names (which he/she probably has memorized). However Mail.app apparently
doesn't let you specify the font size for the message headers displayed
before the message body; I can't find a preference that allows you to
change that.

I think the best way to address this problem in a cross-platform way
would be to fix Thunderbird to act more like Mail.app.

Change Font Size In Thunderbird Inbox Outlook

Was great. Stop complaining about it being gone. Research and fix the problem yourself.
See https://support.mozilla.org/en-US/questions/1198055
'Use the userChrome.css file for both Thunderbird and Firefox on my Linux boxes, since support for this add-on in Linux was dropped some time ago.
Create a folder in your Firefox profile named chrome
In this folder, create a text file named userChrome.css
In that file place the following code:
/*
* Do not remove the @namespace line -- it's required for correct functioning
*/
@namespace url('http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul'); /* set default namespace to XUL */
/*
* Make all the default font sizes 9 pt:
*/
* { font-size: 9pt !important; }
Obviously, edit that font-size: 9pt !important; to a value that suits you. I generally use the same point size as was selected in the OS's desktop settings. You can also set the font face here, e.g.
/*
* Make all the default font sizes 9 pt:
*/
* {
font-size: 9pt !important;
font-family: Arial !important;
}
A similar file named userContent.css in the same chrome folder can be used to set the size of the content of webpages (and of email if used with Thunderbird.)'
