Out-of-the-Box accessible font size for Thunderbird

[RayGulick]

On installation, font size on the inbox pane is terribly small, causing most people over 45 to strain to read it. There is not an easily discovered way to increase font size (another thing that deserves attention but not the subject of this suggestion).

SUGGESTION: Default setting for layout.css.devPixelsPerPx is -1. The default should be increased to 2.5 to make the font more readable for adults middle-age and above.

The use of layout.css.devPixelsPerPx  was deprecated in Thunderbird V102 and actively causes issues for many if set to anything but it's default value in V115.  This is especially so for those using apple products, generally those using retina displays that took advantage of changing the default historically.

The appmenu has a simple font size setting, which I think is easily discoverable.
