Easy Browser is one of the most small and fast browser on Android.
Easy Browser is smaller than Opera mini Browser and Skyfire Browser, faster than UC Browser and Maxthon Browser, simple than Dolphin Browser and Boat Browser, easy than Nine Sky Browser and Tencent QQ browser. you can try whether it is more powerful than Firefox Browser:)
Easy Browser works well with most of the famous website such as Google, Apple, Amazon, Facebook, twitter, Baidu, Tencent QQ, Wikipedia, gmail, Google map, yahoo, Bing, Linkedin, wordpress, discuz and the official website of many famous app/games such as Instagram, Angry Birds, Draw Something, Fruit Ninja and so on. Unfortunately, I can't test Google+ and Google drive due to GFW in China. Great thanks if you can test and feedback to me. As for Youtube, if your native browser support flash, then Easy Browser also support, otherwise not.
Easy Browser can download almost all the link, mp3 and images in the web page you opened. It use 3rd party File Manager(such as ASTRO File Manager) to manage downloaded files. But it is better to install ES File Explorer for downloaded file management.
