They just renewed the contract with Mozilla. That's got nothing to do with it. And there's not nearly enough competition in browsers. Sure, there are lots of projects, but few of them are serious contenders for the average Windows user -- maybe Opera and Firefox qualify, but that's about it. If you've ever tried to write a complex web app you immediately bang your head against the low, low ceiling afforded by the browser. Google knows this as well as anybody and it impedes adoption of Google apps like Gmail or Docs. Making the browser into a better platform is good for their business -- note they are giving away their spiffy new JS engine and the whole thing is open source. If Firefox adopted their innovations tomorrow or one-upped them, I'm sure the Chrome team would be very happy.
