245468 - Font size auto-adjustment, based on document contents

Status: RESOLVED DUPLICATE of bug 31961

(Core :: Layout: Text and Fonts, enhancement)

Many poorly designed pages change the default font size, making the pages
difficult to read. Rules in userContent.css don't always solve such problems.

Mozilla should provide options to be able to adjust the default font size
automatically, based on the contents of the HTML document. For instance, if most
of the text not in headings (> 50%) is smaller or larger than the medium size,
Mozilla should zoom the text (like with <Ctrl>+ and <Ctrl>-) to render it at the
medium size (and the remaining text proportionally).

Note: Of course, this is only a heuristic, and this may "break" the rendering of
some pages (perhaps not properly designed). But if this can improve the
readability of many pages, this is interesting.

Bug 31961 asks essentially the same thing except not automatic.

Automation is also discussed there, see 
http://bugzilla.mozilla.org/show_bug.cgi?id=31961#c3

I guess this should be marked as duplicate.
