firefox is vulnerable to spoofing attacks. An attacker could exploit this vulnerability by tricking a user into visiting a malicious website. If the user is using a vulnerable version of Firefox and enters full-screen mode, the attacker could prevent the user from exiting full-screen mode. This could then be used to launch a spoofing attack, such as displaying a fake login screen or phishing page.
