Auto Refresh Actual Webpage is an application (or website) that can be used to automatically refresh the page you are currently viewing without having to manually refresh the page. This can be useful for when you are waiting for a page to update, such as waiting for a new item to appear in an online store, or waiting for a new post to appear on a social media feed. The app allows you to set the refresh interval, so that you can be sure that the page stays up-to-date without having to manually refresh it all the time.
Discontinued It appears that the extension is no longer updated and does not work in Firefox 57 and later versions.
