The GNOME Web browser (formerly named Epiphany)
'Web' is the web browser for the GNOME desktop and for elementary OS, based on the popular WebKit engine. It offers a simple and clean view of the web, featuring a built-in adblocker (enabled by default), and 'Intelligent Tracking Prevention' to protect your privacy.
With no useless widgets or wasted space, Web fits GNOME's and Haiku's design philosophy.
Its code name is Epiphany.
