Developed for the Mozilla Firefox platform, Stop Autoplay is an extension which disables websites from automatically playing music or movies when you access them. It can be easily installed and configured, even by inexperienced users.
In order for the changes to take effect, you must restart the web browser. Stop Autoplay comes with several configurable options. Thus, you can either disable only the automatic startup of embedded media or the entire embedded media when loading a page.
In addition, you can make Stop Autoplay block all Flash and Microsoft Silverlight media. Restoring settings to their default values is possible.
On top of that, you can create a whitelist, show a controller for hidden embedded music and set its size, as well as set Stop Autoplay to convert the tag and to hide the frame when blocking the media.
The simple-to-use app does not put a strain on the computer's resources, as it runs on a very low amount of CPU and system memory. It is very responsive to commands and didn't cause the operating system to freeze, crash or pop up error dialogs. All in all, Stop Autoplay can come in handy when you want to personalize the behavior of your web browser.
