Go to pilatch.com/cards and click any of the cards in the arc. Now do the same in Chrome, or Safari, or IE 9. I have un-min-catted all my JavaScript, so you can see what's going on more easily. CSS3 transforms in version 16 of FireFox are being converted into matrix transforms. It pretty much horks my rotate and scale animations. For instance, if you set the style attribute of an element to something like, style="transform:scale(0.75)", FireFox immediately converts that element's transform property, such as <element>.style.transform to "matrix(...)". I know how to do the linear algebra to convert rotate and scale via jQuery cssHooks into matrix transformations, and I've even written code to detect this "feature" of a browser, (that it forces a transform into matrix), and return a different hook that writes a matrix transform instead of a rotate transform, or scale, all in the past two days, on my development site. However, it's proving to be increasingly challenging to make this new feature compatible with jQuery's animations. Going further, I may have to hack jQuery just to make this work for FireFox, or drop FireFox animation support altogether unless some FireFox developers make their new implementation backwards compatible. I know that transforms normally get converted into matrices behind the scenes in the rendering engine. Leave your matrix there. Don't overwrite what the user has put in for a transform! I also know that I should be using CSS3 animations, but, dangit, I started this project before those had widespread support. I can't rewrite all my animations because I want to support FireFox. That's not really an option. I'll direct my users to Chrome instead. I have more features in development that use these types of animation, and I'm in too deep to turn back.
