In a monthly web standards newsgram, HP recommends testing webapps in Firefox. They note that after IE6, Mozilla based browsers are the second most popular UAs that hit HP.com. That’s very interesting, since that means we must be beating out even older revisions of IE.
They put it pretty well: “Make sure your Web Section is as smooth and polished in Firefox as it is in IE. Don’t let your customers find your bugs first!”
It’s great to see this kind of enterprise adoption catching on.
