To my surprise, I found out while installing Fedora 8 on a new laptop, that the stix fonts have made their appearance as a rpm package in the Fedora distributions as a bundle:

• stix-fonts-variants.noarch : STIX scientific and engineering fonts, additional glyph variants
• stix-fonts.noarch : STIX scientific and engineering fonts
• stix-fonts-pua.noarch : STIX scientific and engineering fonts, PUA glyphs
• stix-fonts-integrals.noarch : STIX scientific and engineering fonts, additional integral glyphs

Since 2007-12-05, the nightly builts of Firefox prefers the STIX fonts if installed. This is good of course however most users update their browsers with automatic updates and do not install manually the nightly builts, so most users will still need to wait. As a follow up exercise to my STIX experiments, I wanted to check what was done to enable the STIX fonts in the nightly built. Here is a log.

David's blog post on the new stix fonts prompted me to test replacing the standard fontset used by firefox to display MathML. To do that, follow the detailed instructions by R. Sidje on how to add the math font preference to your prefs.js

user_pref("font.mathfont-family", "STIXGeneral, STIXGeneral-Italic, STIXGeneral-Bold, STIXGeneral-BoldItalic");
