# Page-Visibility-User-Script

Prevent websites from knowing if you have opened a new tab/window or if you are using a different application, etc. This userscript blocks the page visibility API and to some extent the old blur/focus APIs.

Example: Twitter stops playing videos as soon as you switch tabs. This userscript prevents that.

## Instructions

* Install a userscript extension like Violent Monkey.

* Open the extension settings, hit install from URL.

* https://raw.githubusercontent.com/IceWreck/Page-Visibility-User-Script/master/pagevisibilityuserscript.js

* Confirm Installation.
