If you want to prevent videos from autoplaying in your Firefox 
, you can disable HTML5 Autoplay and Adobe Flash Player 
.
- Open Firefox .
- Type about:config in the Address Bar and the hidden configuration settings will load.
- Now search for the media.autoplay.enabled setting. Change that setting to False.
Secondly you should block Adobe Flash Player to stop Flash videos from autoplaying.
- Open Firefox .
- Click on the Menu and click Add-ons.
- Click on Plugins and then click on Ask to Activate.
