Non-free software repositories are not provided by the gNewSense project, and most non-free documentation and artwork have been removed. While it was based on Ubuntu, the "Universe" package repository was enabled by default. In order to avoid trademark problems that stem from the modification of Mozilla Firefox, gNewSense 1.1 rebranded it as "BurningDog". BurningDog likewise does not offer to install non-free plugins for various web media, such as Adobe Flash. gNewSense 2.0 abandoned BurningDog and adopted the Epiphany web browser (later renamed simply "Web"), a component of GNOME, as its default browser application, and came with recommendations and instructions to optionally compile and run GNU IceCat. gNewSense 3.0 retains Web as the default browser, but also comes with a modified version of Debian's Iceweasel that does not offer to access proprietary add-ons.
