IIRC the situation is that IE simply doesn't support rounded corners, but some other browsers need browser-specific extensions... either FF or web-kit, I don't recall.

I'm happy to use it in some cases and let IE fall-back to square corners, but does using browser-extension CSS break validation... I quite like having my site validate AND work on IE6.
