From the www-style style mailing list:
"Maybe if browsers ship with a minimum font size . . . out of the box . . . web
designers will realize that they have misunderstood what their readers want and
that the browser window isn't something they control, but something they share
with millions of other people."
Bug 209879 gave this to Camino users. We should give this to all users.
My personal preference is to set it to 11px. 11px is the closest integer under
70% applied to our 16px default. 70% is from
https://bugzilla.mozilla.org/attachment.cgi?id=125604 as it would apply to
we set the default scaling factor (sFontSizeFactors) for size xx-small.
I realize this will break some pages that set container sizes in px, but believe
that in effect those pages are already broken both when users have set their own
minimums and/or when they zoom, since the resulting overlapping or hidden text
really isn't any less useful than too small text.
Bug 286255 is same bug for Firefox
