What it is

⚠️ Firefox versions below 66 harbor some sneaky memory safety bugs that could lead to memory corruption — a potential playground for attackers! 🤔 Think of this like a restaurant kitchen where some of the ingredients have been mislabelled. If a chef doesn’t catch those errors, they might serve up a dish that goes horribly wrong! 🍽️ With enough effort, a crafty attacker could exploit these memory issues to run arbitrary code on affected systems. That could mean anything from compromised user data to total control over the browser. Yikes! 🚨
