Direct quote from the page at the other end of this link :
"You appear to be using a browser that may not be able to display our site correctly. Generally, this is beause it's an older browser that doesn't support a lot of the newer, awesome features in open Web standards.
Rather than provide an untested and possibly subpar experience of our site, may we suggest downloading one of these fine browsers? (We think you'll find your overall experience of the Web will improve if you do.)"
This is followed with links for Firefox and Chrome. I am running Firefox 24.4 from CentOS repos. This is unskippable, and there's no simple way to bypass it on the page. On a browser from March of this year.
Urgh.
