firefox is vulnerable to Spoofing Attacks. The vulnerability occurs when a website uses the window.open()
function to open a new window. If the new window is opened in full-screen mode, the malicious website can use the document.querySelector()
function to find the full-screen notification and then obscure it with a malicious overlay. This overlay can then be used to display a fake notification that could trick the user into taking some action, such as entering their personal information or clicking on a malicious link.
