Back in August, Mozilla took the WBGP crown with Firefox 7. Can Firefox 9 retain that title? And how are the top Web browsers doing in Mac OS X? We used a Hackintosh last time. This time, we're testing on the world's first Ultrabook, the MacBook Air.

Last August, we ran the Web Browser Grand Prix (WBGP) in an entirely new venue. The title was Web Browser Grand Prix VI: Firefox 6, Chrome 13, Mac OS X Lion, and we used the same desktop test system we always use, but Hackintoshed. Despite the fact that an OS X browser took first place in nearly one-third of the tests, some of the more, er, enthusiastic Mac fans weren't very happy with our platform choice. They set down their Starbucks double venti caramel macchiatos to complain, “But Adam, that's not a real Macintosh, so of course OS X on a PC is going to suck compared to Windows” and “why didn't you run it on a MacBook with Parallels?” and (my all-time favorite) "it's not fair!"

The short answer is that we don't have a ton of Macs in our PC-centric labs. Nevertheless, we went out and bought a brand-new 11” MacBook Air specifically to satisfy the folks who want to see browsers tested on their native platforms. Welcome to Web Browser Grand Prix VIII, the Mac rematch!

But before we dig our heels into this Mac versus PC Web browser battle royale, let's get everyone caught up on the latest events and ensuing drama. More than two months have passed since we published Web Browser Grand Prix 7: Firefox 7, Chrome 14, Opera 11.51, and a lot has happened in the browser wars since then.

Wow, what a couple of months! Mozilla seems to realize that Chrome is the real threat, as Google becomes the number two Web browser, and all of the top three continue with their antics. Meanwhile Apple remains silent on the browser front, and Opera has some really big changes in store for 2012.
