Test Always Active

Some websites only function when the user is active, meaning when the page is not hidden, such as music websites. Others only render the page when it is active and stop updating content when the tab is hidden. While this can be a useful feature, it might not suit your preferences. If you have an always-active extension, you can use this page to test its effectiveness.

What is Test Always Active?

You can use this page to test whether your always-active extension successfully blocks hide-related events. First, turn off the extension and refresh the page. Press the start button to observe events related to page leave and page hide. Then, turn the extension back on and retry. If your extension provides effective active protection, it should block all hide events.

What is the meaning of "requestAnimationFrame (ms/sec)" feature?

This feature uses the built-in function to count the number of frames the browser processes for page rendering. Typically, when a tab is hidden, the browser either stops calling the callback or significantly reduces its frequency. The feature is disabled by default as it degrades performance. If you want to try it, be sure to use the stop button to disable it after testing.
