Is there anything like the Theme Font Style Changer in the latest version of Thunderbird?

Very sad indeed! So, how does one read the tiny text on the inbox page etc?

Are you asking abut the text in the message list pane? If so, see this article is still helpful -- http://kb.mozillazine.org/Pane_and_menu_fonts

The opening page with the subject / Date / Size / From etc. Also the left folder pane. I'm not sure what "tree" refers to those?

the left folder pane.

Seems that would be #folderTree > treechildren {font-size: 12px; font-family: Arial;}
The opening page with the subject / Date / Size / From etc

Wouldn't it seem that might be #threadTree > treechildren {font-size: 12px; font-family: Arial;}

On Windows 10 I set my Display setting in Windows settings to 125%.

Applies to all applications which is just fine with me.

On Linux I installed Tweaks and set the UI font size to 13.

OK...It seems the "simplest" solution is to use Config Editor and go to "layout.css.devPixelsPerPx and change the Pixel size. I suppose that will change the size of the message and folder pane text size....and nothing else. Am I correct?

Nope. It will change the size of all characters in Thunderbird. It will have no effect on other applications.

Is there a way to just change the message and folder pane size (without affecting the message text size etc?)

If you want to change the size of the characters in the folder pane and folder listing but NOT the text within a message see the link Dan gave you in his first post - http://kb.mozillazine.org/Pane_and_menu_fonts - and look in the Trees section.

You'll need to create a userChrome.css file and set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true using the config editor. The latter is required for recent versions of Thunderbird to pay attention to userChrome.css or userContent.css. That requirement didn't exist when the KB wiki was frozen, so the KB article doesn't mention it.

You mean add this to the chrome folder: "userchrome.css) ?

#folderTree > treechildren {font-size: 12px; font-family: Arial;}
#threadTree > treechildren {font-size: 12px; font-family: Arial;}
#dirTree > treechildren {font-size: 12px; font-family: Arial;}
#abResultsTree > treechildren {font-size: 12px; font-family: Arial;}
