Pale Moon: Firefox Without DRM, Interface Breakage
Written by Michael Larabel in Mozilla on 22 May 2014 at 09:21 AM EDT. 37 Comments
For those upset with Mozilla's recent decision to add EME / HTML5 video DRM support to Firefox, the "Pale Moon" fork of Firefox may be of interest.

Pale Moon is a fork of Firefox for Windows and Linux, but it doesn't come down to a silly theming fork or other basic changes. The fundamental differences between upstream Firefox and Pale Moon is that they will not be implementing HTML5 DRM/EME support, they are sticking with the original Firefox interface rather than the new Australis UI, and they will not be accepting sponsored ad pages / tiles.

The Linux builds of Pale Moon right now comes from a PM4Linux project build while Windows appears to be the project's primary focus.

If you're interested in the Pale Moon web-browser, stop by The same developers behind Pale Moon also have as their fork of the Mozilla Thunderbird mail client.
