Always active Window (Always Visible)插件简介

Always active Window (Always Visible)插件描述

By installing this extension a small script is injected into every webpage which overwrites the "document.visibilityState", "document.hidden" properties to pretend the tab is always in the active state (document.visibilityState = visible  document.hidden = false). This is useful f the webpages that check your visibility state befe loading resources like many music webpages. By installing this extension even if the page is opened in the background page, the player will start immediately like the page is loaded on an active tab. Note that this extension also suppts "document.mozHidden" on Firefox  "document.webkitHidden" on Chromium browsers. Also, it blocks the "visibilitychange", "webkitvisibilitychange",  "mozvisibilitychange" events that are emitted when the page visibility status changes.

Note that at the moment there is no exception list, so the extension injects the script on all HTTP  local HTML pages. You need to disable the extension from the options page if you need to bypass it.
