Pretend that all browser windows are active by spoofing the visibility state event

Always Active Window Add-On for Firefox
"Always Active Window (Always Visible)" is a Firefox add-on that tricks web pages into thinking your tabs are always active. By modifying the visibility state properties, it ensures that background tabs can freely load content and services, particularly useful for media sites that check whether a tab is active. The extension injects a script into all web pages, making them behave as if they're in the foreground, bypassing restrictions imposed by many websites.
