Google has had a relationship with Mozilla Firefox for quite sometime and now they decided to branch off and get in to the desktop applications at a larger level. Firefox lead engineer Ben Goodger began working on the Google Chrome project two years ago where at that point, he stopped contributing to Firefox. Firefox see’s Chrome as another competitor in the industry, and why shouldn’t they, its Google.
Chrome is designed to have more application related websites run smooth giving each browser tab its own run-time environment so if one tab crashes, you can still continue to browse other websites in separate tabs.
