No proprietary plugins. No DRM.
Firefox shouldn’t even have a EULA. Mozilla should be collecting ZERO information from the browser that they cannot collect from httpd logs.
To quote Mozilla co-founder @jwz
“In my humble but correct opinion, Mozilla should be doing two things and two things only:
1. Building THE reference implementation web browser, and
2. Being a jugular-snapping attack dog on standards committees.
There is no 3.”
