Thanks Matt. You had the right idea in your about:config comment,
although the setting name and value turned out to be a bit different.
I finally got what I needed from support.mozilla.org and the setting
name was layout.css.devPixelsPerPx and I had to bump it up to 1.3
to get a font size closer to what I see with the chromium browser.
