In Firefox your can open Web Inspector (Ctrl+Shift+c), point to text and 
then view in Font tab which font is actually selected by Firefox for 
given text.

If it shows:
Foo Bar system
used as Helvetica

your can check via
$ fc-match 'Foo Bar'

which font file selected by fontconfig for this font name.

Is font shown by fc-match is TTF/OTF font?

If your don't have Geneva,Helvetica,Arial fonts installed your can 
create aliases in fontconfig xml config, see e. g.
https://seasonofcode.com/posts/how-to-set-default-fonts-and-font-aliases-on-linux.html
I also use aliases for common font family names, but prefer other fonts.

Is in "Print Preview" text rendered in readable form?
