How to Stop YouTube Videos from Automatically Playing in Firefox
It drives me crazy that YouTube videos start playing automatically. It’s especially annoying when i try to download youtube Video using Realone Player .So I went searching for the best method to disable these videos from playing automatically, and came up with three different options that I’ve listed for you here.
Method 1: Using the StopAutoPlayingAlready Extension
To install, download the extension to your hard drive, and then drag it to your Firefox Add-ons dialog:
Download Youtube Prevent Autoplay Script from userscripts.org
Method 3: Using the Stop Autoplay Extension
This extension will not only stop Youtube videos from auto-playing, but will stop all embedded media from playing automatically. Note that if you use this extension you really don’t need the other solutions.After installing this extension, you’ll notice that the video is completely gone from the page.
Once you click on the video, it will then load and then start playing. Enjoy!
