Canonical founder Mark Shuttleworth says there is "a real possibility" that Chrome will replace Firefox as the bundled browser in future distributions of the Linux operating system.
But I think Firefox is better than Chrome, because Firefox support plug in feature than Chrome. But performance wise Chrome is better than Firefox.
In terms of speed, Chrome takes the lead. I am quite sure Mr. Google is cooking something behind its door to control the browsing world. Now, Flock has reached its extinction, referring people to Chrome and Mozilla Firefox browsers. The possibility of merging the two browsers is imminent.
