Font became tiny and it's impossible to use the program. No way to change font since last update almost half a year ago .

A great add-on when it works. But the original add-on failed due to a date expiration, and next one failed 3 months later apparently for the same reason. Avoid the aggravation and install the non add-on fix from Mr. Bob. Simple and easy fix with no date expiration. Have used on 2 TB accounts on 2 Win 10 laptops with no issues. Font size is now adjustable again. Thanks Mr. Bob!

After downloading and adding this add-on, it is listed in both Firefox and Thunderbird as being enabled, but there is no place to actually find and work with the add-on i.e. change the application (NOT the message composition) font sizes. If I can't solve this problem real soon, I'll have to kick both Firefox and Thunderbird through the goalpost of life - can't read the toolbar and message pane script in Thunderbird. Apparently the default download for Thunderbird for the latest Windows 10 is a32-bit version 52.7.0 with which nothing seems to work properly and for the default 64-bit version of Firefox for Windows 10 called "Quantum," this add-on doesn't work. Please don't bother flaming me for these comments. I do know what I'm talking about

Your font size on Thunderbird is unusable. Wake up or piss off altogether you bunch of nerds

Noticed, as others did that it stopped working again. I uninstalled the add-on and reinstalled the patched xpi we made from happyone back in Jan and the menu is back. Just need to keep automatic updates off and remember to update the addons you want yourself.

I still prefer the addon since it has more controls over the manual hack.

Unfortunately this add-on stops working every 90 days or so, so has become problematic for me. However I have done what Mr. Bob suggested and that works fantastic. 5 stars for Mr. Bob!

again not working correctly. Why - I don't know.
And I'm tired of this crap.
Why isn't there any alternative?

The directory for Linux is:
/home/Username/.thunderbird/xxxxxxx.default
And add the chrome sub-directory to that. This may also work on iOS.

Where can I find a list of entries like font-size and font-family?

The Theme Font Size Changer stops working every time I have an update to my OS. I see the instructions for the workaround you posted, but it looks like for a PC. How do I do it on my Mac? My eyes are killing me since the Add-on stopped working.

My Theme & Font Size Changer stopped working again today (April 9). I followed your instructions, chose a font size of 14, and now my font size is good without using an add-on. Thank You!

Thanks Mr. Bob! This did the job for my olde eyes. And for those folks that think adding a prewritten script is 'programming', cut-and-paste is a more appropriate characterization.

Locate this folder:
C:\Users\YourName\AppData\Roaming\Thunderbird\Profiles\xxxxxx.default

within the xxxxxx.default folder created a folder and call it chrome

open the chrome folder and add a new text document and name it userChrome.css

now open userChrome.css with notepad

paste the following code exactly:

/*
* 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;
font-family: Arial !important;
}




Note: change the font size and font family to your liking
Note: you must restart Thunderbird for changes to take effect.
