Google and Mozilla Release Critical Security Updates for Chrome and Firefox

Security Week · 19 Aug 2026
Key Takeaway Make sure Chrome and Firefox are set to update automatically, and encourage staff to restart their browsers regularly so security patches take effect.

Google and Mozilla have released new updates for Chrome and Firefox, patching dozens of security vulnerabilities across both browsers. According to reports, the flaws could potentially allow attackers to execute malicious code, escalate privileges, escape the browser's security sandbox, or access sensitive information without authorisation.

Browsers are one of the most frequently used tools in any business, making them a common target for cybercriminals. Vulnerabilities like these can be exploited simply by a user visiting a compromised or malicious website, without any other action required, making timely updates especially important.

Both Google and Mozilla regularly release patches to address newly discovered issues, but these updates only provide protection once installed. Businesses that delay updates leave a window of opportunity open for attackers who are aware of the specific vulnerabilities being fixed.
