The Gecko Layout Engine added Graphite Smart Fonts support starting in Firefox 11. The Mozilla Firefox documentation for Graphite is still under construction but already contains lots of useful information for Web Designers and Developers. The number of people who will benefit from Graphite is the small subset of the population that reads and writes with lesser-known scripts that require complex ligatures and rules for glyph substitution. In other words, we expect this work will appeal to a rather small underrepresented percentage of the web who communicate using uncommon writing systems.
