Epiphany displays webpages with the same speed and accuracy as other popular browsers, such as Safari or Firefox. In addition, it provides an elegant, responsive and uncomplicated user interface that fits in perfectly with GNOME, and it has been translated to over sixty languages!
Customizable user interface
Epiphany lets you arrange user interface elements by simply dragging and dropping with your mouse. It also provides tabs, so you can easily organize related webpages on your computer screen.
Smart bookmarks make it a snap to lookup text in online knowledge bases, like dictionaries or search engines. Also, you don't have to keep track of in which subfolder you put that one bookmark --- just assign it some topic(s) and Epiphany will show you the relevant bookmarks in a dropdown menu.
Extensions and plugins
Need some specialized browser function that's not available in the default menus? There's a good chance someone has already written an extension for you. The Epiphany Extensions package is what you will need. Epiphany runs all the same popular plugins that run in Mozilla.
