Problem with Iceweasel and low-quality fonts



In the Iceweasel preferences, I have the "Allow pages to choose their
own fonts, instead of my selections above" option enabled. But the
quality of the fonts is sometimes very low, a bit like bitmap fonts,
without antialiasing.

For instance on http://www.allocine.fr/ see what I get on the image
I've attached, for "A ne pas manquer". The FontFinder extension says:

Font
===============================
font-family (stack): Tahoma,Lucida,Arial,sans-serif
Font being rendered: Tahoma
font-size: 24px

$ fc-match Tahoma
Vera.ttf: "Bitstream Vera Sans" "Roman"

which is actually my default font. So, where does the problem come from?

Note: I have a similar problem on some other pages, where the font
is Helvetica. But this time:

$ fc-match Helvetica
helvR12-ISO8859-1.pcf.gz: "Helvetica" "Regular"

which is a bitmap font. How can such bitmap fonts be disabled for the
web browsers (only)?
