If I understand you correctly, the fonts within the displayed web pages 
are "correct" according to what you want, but the application user 
interface fonts are not.

You want fonts smaller than "X" to not be anti-aliased in the 
firefox/thunderbird UI.

NOTE: You stated the reverse of the above, but since anti-aliasing makes 
a complete mess of small fonts, I suspect you want the reverse of what 
you said, namely disabling anti-aliasing on small fonts.

There are two things you can do to fix the matter:
1.) Over-ride the anti-aliasing in /etc/fonts/fonts.conf (or 
~/.fonts.conf) for small fonts (and/or specific font names).
2.) Force specific UI fonts/sizes via the UserChrome.css file for both 
firefox and thunderbird.

Also, you might want to check out "about:config" in the firefox url bar 
and look up the "font.antialias.min" setting. This is most likely what 
is preventing anti-aliasing on small fonts, but I'm uncertain if it 
affects only displayed web pages, or web pages and the UI.
