It's still important to test a bit on Firefox and Safari, or you'll have the occasional UI bug. I found one earlier today where Firefox behaved differently than the other two and needed a quick fix. I'd say this happens once every few months Times have changed in that you won't have layers and layers of branching logic to work around browsers that aggressively disagree with each other. But Chrome tends to fudge the web standards in some of their dark corners, Firefox tends to stick to the letter of the web standards rather than the spirit, and Safari tends to have random little gaps and quirks Your UI will probably be usable without cross-browser testing (assuming you're not doing anything exotic), but it will probably have little things here and there that aren't quite right
