Dolphin is a free, fast, smart and personal web browser. It has lots of features like multiple tabs bar, bookmarks & add-on sidebar, incognito browsing, personalized search, fast download, gestures etc.
It is fast, stable and smaller in size. The best part is that it is available for a number of operating systems.
Though one of the best browsers, it crashes a lot and does not seem to work at all when the internet is slow.
