Firefox via Pango uses fontconfig. While "xset fp" or FontPath in
xorg.conf are still supported they rarely look good. Check fc-list or
fc-match instead. For one, to replace default sans-serif font try

$ mkdir -p ~/.config/fontconfig/conf.d/
$ cat <<EOF >~/.config/fontconfig/conf.d/50-local.conf
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "../fonts.dtd">


$ fc-match sans
Roboto-Regular.ttf: "Roboto" "Regular"

$ firefox

Read fonts-conf(5) manpage for more details.

If a web page still uses a different font open "Inspect Element", check
what CSS rule requested and adjust fontconfig. For one, you can configure
for Arial to be displayed as Roboto. ;)

Removing unused fonts is another option.
