  • The similar issue
    Please run the following code in the extension’s sandbox:

    var e = {
        bubbles: true,
        cancelable: true,
        view: window,
        detail: 0,
        screenX: 0, 
        screenY: 0,
        clientX: 0, 
        clientY: 0,
        ctrlKey: false,
        altKey: false,
        shiftKey: false,
        metaKey: false,
        button: 0,
        relatedTarget: undefined
    };
    var evt = document.createEvent("MouseEvents");
    evt.initMouseEvent('click', 
        e.bubbles, e.cancelable, e.view, e.detail,
        e.screenX, e.screenY, e.clientX, e.clientY,
        e.ctrlKey, e.altKey, e.shiftKey, e.metaKey,
        e.button, document.body.parentNode);
    

    Edge throws an error Unspecified error.
    at the code "initMouseEvent()"
