Type confusion is a vulnerability that arises when a program or script incorrectly interprets a data type, leading to unexpected and potentially dangerous behavior. In the context of web browsers, type confusion can be exploited by attackers to execute arbitrary code on a victim's machine.

This vulnerability could allow an attacker to execute arbitrary code on a victim's machine by tricking them into visiting a malicious website or clicking on a malicious link. The vulnerability was caused by the way Firefox handled certain JavaScript objects in memory, which could lead to a type confusion error.
