使用JavaScript背景脚本关闭窗口？ （Firefox扩展程序）

Question

I am currently writing a Firefox extension that opens a new window in my background script. When a user clicks a button on a page the background script executes and opens the window.

So far I have:

// content script
downloadMod(linkToOpen); //button clicked
function downloadMod(url) {
    // var test = window.open(url, '_blank');
    var myPort = browser.runtime.connect({ name: "cac410c4672fff93bf0d3186636d8876de3dfeb6@temporary-addon"});
    myPort.postMessage({ greeting: url });
}

In my background script (the script the above code connects too) I have:

//background script
portFromCS.onMessage.addListener(function (m) {
        var test = browser.windows.create({
            url: m.greeting,
            allowScriptsToClose: true,
        });

NOTE: all the code works as expected. However, the trouble comes when closing the window.

I have tried variations of self.close() , window.close() . I even created a function to wait 5 seconds to load the newly created window and then close the page to no avail. All of my attempts come back with the error:

Scripts may not close windows that were not opened by script.

I thought this error was supposed to be removed with the allowScriptsToClose flag?

To close a window you created with browser.windows.create, you need to use browser.windows.remove.

So:

let windowId;

browser.windows.create({url: "http://google.be"}).then((data) => {
    windowId = data.id;
});

// Sometime later, use windowId to close the window
setTimeout(function(){
    browser.windows.remove(windowId);
}, 5000);
