I posted about this in the Mijireh forums, that I’m also struggling with this…. My custom CSS3 fonts on my checkout page work fine on Webkit, but not Firefox. I’ve tried using direct link to the font in CSS, and also using “https” with no luck.
Would someone mind sending me a link to a working website that is using custom fonts on a Mijireh checkout page, that works in FF? Perhaps if I could see a working website as an example, I could follow suit with the way it’s calling the fonts in the styles CSS. Thank you.
