= Proprietary Extras =
Proprietary software helps you maximize your Internet experience, but is not open source. The software available includes Multimedia Codecs, Java Runtime Environment, and plug-ins for Firefox.

== Restricted Extras ==
The Ubuntu Restricted Extras will install Adobe Flash Player, Java Runtime Environment (JRE) (sun-java-jre) with Firefox plug-ins (icedtea), a set of Microsoft Fonts (msttcorefonts), multimedia codecs (w32codecs or w64codecs), mp3-compatible encoding (lame), FFMpeg, extra Gstreamer codecs, the package for DVD decoding (libdvdread4, but [[#DVD Playback Capability|see below]] for info on libdvdcss2), the unrar archiver, odbc, and cabextract. It also installs multiple "stripped" codecs and avutils (libavcodec-unstripped-52 and libavutil-unstripped-49). This is a single command approach. 
 sudo apt-get install ubuntu-restricted-extras

Note: Installation only works completely and properly when done from the command-line Terminal. The entire package will not usually install completely from within a Package Manager.
