Conditional Comments Firefox

问题:

Are there specific Conditional Comments available for older versions of Firefox? (eg 3.0)

回答1:

No, they are only supported by IE.

There are CSS hacks though. See: http://perishablepress.com/press/2009/06/28/css-hacks-for-different-versions-of-firefox/

回答2:

Not to my knowledge. As far as I know, conditional comments are an Internet Explorer-only feature.

QuirksMode.org agrees.

回答3:

I am trying to create a solid fallback for @font-face by initiating Cufón for older browsers. Conditional comments came to mind but perhaps there is another route?

You just have to inject the cufón script tags conditionally.
