Relax, this is for fun Rated 5 out of 5 stars
If you are thinking about using this add-on, keep these things in mind.
1) It's for fun, and not some sort of magical NSA/Prism blocking add-on.
2) Purchase Pink Floyd's Dark Side of the Moon album if you want to pause, mute, etc, the songs.
3) Here's a list of the companies, http://www.pcworld.com/article/2040991/report-nsa-prism-program-spied-on-americans-emails-searches.html
4) Firefox button > Add-ons > Extensions > Dark Side Of The Prism > Disable, disables this add-on or you can choose Remove.
This is a brilliant and funny add-on!Thanks for developing it.
