This method cannot be used in Private Browsing mode — it always returns an empty array. Consider using
runtime.sendMessage()

runtime.connect()

var page = browser.extension.getBackgroundPage()
None.
对象
.
Window
of the background page.
Suppose a
background script
defines a function
foo()
:
// background.js
function foo() {
console.log("I'm defined in background.js");
}
A script running in a popup can call this function directly like this:
// popup.js
var page = browser.extension.getBackgroundPage();
page.foo(); // -> "I'm defined in background.js"
BCD tables only load in the browser
