Conditional Comments Firefox

Question

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

Solution 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/

Solution 2

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

QuirksMode.org agrees.
