This works for me in all browsers!

viewPdf(base64String) {
    let byteCharacters = atob(base64String);
    let byteNumbers = new Array(byteCharacters.length);
    for (var i = 0; i < byteCharacters.length; i++) {
        byteNumbers[i] = byteCharacters.charCodeAt(i);
    }
    let byteArray = new Uint8Array(byteNumbers);
    let blob = new Blob([byteArray], { type: 'application/pdf' });

    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
       window.navigator.msSaveOrOpenBlob(blob, 'Report.pdf');
    }
    else {
       var fileURL = URL.createObjectURL(blob);
       window.open(fileURL);
    }
}
