I set it to 1.4 in about:config, and it immediately took effect without a
restart. There is larger text in the mode-line and minibuffer. I visted
such sites as google and wikipedia, and all of their fonts were scaled up
as well.
The fonts that this pref does not affect are anything sized in px, because
that is an absolute measurement. This includes the fonts in the
about:config dialog itself, which I attribute to poor design on Mozilla's
part. To affect text whose font-size is defined in px, you will need to
set the preferences governing minimum font-size. There are several of
these, but the following two catch most sites:
session_pref("font.minimum-size.x-western", 32);
session_pref("font.minimum-size.x-unicode", 32);
(You will probably want a value less than 32, but if you test it with 32,
you will be sure to see the difference!)
