Since Track Package's
final release for
Firefox in December of 2013, Mozilla has abandoned its own technologies in favor of poor parody of Google's protocols (WebExtensions), leaving many developers, including this one, disillusioned with the direction the Mozilla is taking. In contrast,
Pale Moon has stepped into place as an XUL-centric browser, keeping backward compatibility
better than Mozilla's own flagship project. Track Package is now exclusively a
Pale Moon extension.
