Much has been said about the (perceived) rivalry between Chrome and Firefox, but Google engineer Peter Kasting had enough when he read an article trying to discern Google's true motives
for signing a new Firefox search deal. Kasting posted to Google+ to clarify what value the company sees in funding a "rival" browser
"People never seem to understand why Google builds Chrome no matter how many times I try to pound it into their heads. It's very simple: the primary goal of Chrome is to make the web advance as much and as quickly as possible. That's it. It's completely irrelevant to this goal whether Chrome actually gains tons of users or whether instead the web advances because the other browser vendors step up their game and produce far better browsers. Either way the web gets better. Job done. The end. So it's very easy to see why Google would be willing to fund Mozilla: Like Google, Mozilla is clearly committed to the betterment of the web, and they're spending their resources to make a great, open-source web browser. Chrome is not all things to all people; Firefox is an important product because it can be a different product with different design decisions and serve different users well."
