Firefox 3 bring some impressive new features to text rendering: kerning, ligatures, hinting, and more.
Two great summaries have been written on the topic in the past few weeks:
- Firefox 3: Fonts and text, Stuart Parmenter & Deb Richardson
- Kerning and OpenType features in Firefox 3, Ralf Herrmann
Unfortunately, Ralf’s investigation seems to show that some of the functionality is still a bit buggy in Firefox 3 on the Mac — adding discretionary ligatures automatically, and not using context-sensitive glyphs appropriately.
