Yesterday, Firefox announced WOFF (Web Open Font Format) support will be included in the next release – Firefox 3.6.
WOFF is a compressed font format meaning a better @font-face experience in Firfox through faster font transfers and shorter FOUT times.
Last night, I added WOFF support to Kernest. Now if you’re browsing with one the Firefox Nightly Builds on site using fonts from Kernest – you’ll receive a WOFF instead of an TTF or OTF.
