    var hasBeenCalled = false;
    function doSomethingOnce() {
       if (!called) {
          console.log("I haven't been called before");
          // do fancy stuff.
          hasBeenCalled = true;
       } else {
          // do nothing, function already called.

       };
    };

chrome.cookies.onChange.addListener(doSomethingOnce);

或者更好的是，您可能会找到一个chrome.cookies.onChange.removeListener(doSomethingOnce);，在这种情况下，在您的doSomethingOnce函数中，在您执行任何您想做的事情之后，您调用chrome.cookies.onChange.removeListener(doSomethingOnce);
