Firefox for Android is free to download and use. Before this I have been using Opera Mini for Android and found it to be very user friendly. Firefox lets you have tabbed browsing on your Android device. It takes a whopping 17 MB so you better have enough space on your smartphone or tablet before installing it. But what I liked most about Firefox is the ability to sync my Laptop and smartphone. So now all my tabs, bookmarks, accounts info and even history in synchronized on both devices. This way I do not have a problem when I am using Firefox at home on the lappy or during move in my car.
