Managing message fonts is NOT the issue, which is:

How does one change the font size for lists, etc. - e.g., Local Folders, lists of Emails - that are native to Thunderbird program info display? It's easy to control column content, message fonts, etc, but there seems to be no solution to the overall display size dilemma other than to reduce monitor resolution - and that's NOT a good thing to do!

To state it differently - pretend your eyes are worsening, and you need for default program displays to appear in enlarged format - not just messages, but the entire display, frame, etc. - how to do with TBird?

Try this add on: https://addons.mozilla.org/en-us/thunderbird/addon/theme-font-size-changer/

If you're one of those who desperately dislike addons, what this addon does can also be achieved by editing a native configuration file. The addon will at least give you the ability to interactively try various adjustments.

Works perfectly with 29.0 - I greatly appreciate the help offered by Mozilla, in this case by "Zenos." Keep up the good work!

What config file can i edit? TFASC doesn't work for me on v45.2.0. I'm a long time user of Thunderbird, my eyes are getting worse, and it would be REALLY nice to be able to increase the font size or change to a bold font.

I have a file named userChrome.css located in the chrome folder. You may have to create the folder and this file within it.

Assuming you don't already have a chrome folder, copy the following, paste it into a new text file, name it userChrome.css, make the folder chrome in your profile, copy your new file into that folder, then restart Thunderbird.

If you do already have a userChrome.css, open it in an editor such as notepad, and paste the font-size line into it.

You can change the 12pt !important to suit your needs. I'd check to see what size you set for items in your desktop GUI and use that same value here.

/*  * 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 12 pt:  */ * { font-size: 12pt !important; }

I figured it out. I had userchrome.css in the mail folder, instead of the profile. Thank you much or the help.
