Disable video auto-play in Firefox

If you do not want all those videos auto-playing in Mozilla Firefox then you can just turn them off.

From a tab in Firefox enter the following:


Search for the option “media.autoplay.enabled”  the value should be true click on it to change it to false.  You can now close the tab and you are done.

NOTE (10/10/2017): It would appear the the newest revision of FireFox broke this when they added a new value.  You will also need to change.  “media.autoplay.default”  this is by default 0 change it to 1.
