Firefox fixes security flaw similar to Chrome’s

Mozilla has identified and fixed a serious security flaw in its Firefox browser. This vulnerability was similar to one recently discovered in Google Chrome. Kaspersky first revealed the zero-day bug, which was used in cyber-espionage against targets in Russia. In a security advisory on March 27, 2025, Mozilla explained that the flaw allowed a compromised process to escape a security feature known as the "sandbox." This could potentially let malicious websites access sensitive user data. Firefox users are urged to update their browsers to the latest versions to address the issue. The flaw primarily affects Windows users, while other operating systems remain safe. Mozilla noted that while Chrome’s bug was actively exploited, Firefox's version had not yet been used in the wild.
