It has been a year since iam using firefox and it is better than google chrome. it surfs the internet more fast and its downloading speed is also very good. it is a open source software so you can customize more settings like proxy etc which you cant do google chrome.its setup is not too big so you can download it from its official website.
It is also very easy to install and very simple to use. you can also add many add ons to this browser. the support of the company is also very good if you have any questions you can mail them them and they will reply you soon. the interface is also very good and you can choose any search engine like yahoo or google to work with.
