I forgot to mention, if I use DOM Inspector on say, the select
element, it says this:

font-size           >28.45px
select> -moz-system-font         forms.css:194
form> 18px                            inline:2

The "form" line is greyed out, I suppose indicating that Iceweasel
has chosen to use -moz-system-font from forms.css.

Cheers,
Andy
