I've read the Enlarging the Font for menu bar and tabs.
I cannot find, from the Menu bar, Tools, Settings, General, scroll to bottom to Config Editor I have not been able to find this "Config Editor". I also did not find .css file in that I might be able to modify. I am not understanding why the option isn't present in the settings for Firefox!

It doesn't look like instructions for Firefox. The "Config Editor" button is only in Thunderbird and you can't use it to change CSS variables. They are being changed elsewhere.
To get to the config editor enter about:config in the search/URL bar.
Entered 'about:config' in Version 127.0.6533.101 (Official Build) (64-bit)
