I just came across why Google built a browser.

Google Chrome is by far my favorite browser of the moment. I lost interest in Firefox as it became slower and slower with each update (it takes nearly 10 seconds to load from when I click the icon to launch it!). Additionally, Firefox had tons of memory leaks, and leaving the browser up all night would have my computer at a crawl by the morning.

Chrome loads immediately and my favorite feature is the one-box-for-everything (URL and search in one box).

I recommend you try Google Chrome out if you are looking for an alternate browser.
