Solve the problem that Firefox can't play mp3 under Linux

Kali Linux has been used before, work screen noise are used netease music. Since there is no Linux client, then the web version of it. Have to say, NetEase Music web version do really praise.
　　
Kali Linux under the use of Firefox to listen to the song has been very normal, but some of the site's MP3 on the hiccup, did not care.
　　
Some time ago in the dark clouds spent some WB to redeem a 256G SSD, can not wait to be loaded up, system, it should also change.
　　
Kali Linux as a penetration test artifact, many of the functions of the blogger for some redundancy, simply switch to Ubuntu, consider a while, Bo Master decided to install Xubuntu, after all, using XFCE as a desktop environment, lightweight and fast, although no Gnome has gorgeous special effects, But fresh and clean, that's enough.
　　
System comes with Firefox, bo master lazy to download Xubuntu, used a long time ago downloaded a version, installed the system found Firefox or 28 version, is old enough, and now are 43.
　　
Well, update the system after the automatic upgrade to 43, the egg is a variety of music can not play, at first thought is to install Flash plug-in, after the installation of Flash is still not happy to play, but Baidu Music is able to play normally, is really depressed, bloggers really do not like to use Baidu Music, page do too card.
　　
Pondering how to solve, bloggers try to use the local music player to open the local MP3, the results can not open, it is really weird, prompted to install additional plugins. See these, Bo Master seems to understand what, this thing originally need decoder ah.
　　
Install the decoder decisively, one command

sudo apt-get Install Ubuntu-restricted-extras

After installation restart Firefox, it's done, and you can play happily.
