Epiphany is the default web browser for the GNOME computer desktop.
Epiphany is one of a family of web browsers that use the Gecko layout engine from the Mozilla project to display web pages. It provides a GNOME integrated front-end to Gecko, instead of the Mozilla XUL interface. Like many Gecko-based browsers, Epiphany supports tabbed browsing, cookie management, popup blocking and an extensions system.
Whilst most browsers feature a hierarchical folder-based bookmark system, Epiphany uses categorised bookmarks, where a single bookmark (such as 'Epiphany') can exist in multiple categories (such as 'Web Browsers', 'Gnome', and 'Computer Software'). Special categories include bookmarks that have been used frequently ('Most Frequent') and bookmarks that have not yet been categorised.
Another innovative concept, Smart Bookmarks, take a single argument and can be used from the address bar or toolbars to perform web searches.
