Firefox 21 has been released as an update today, and not only addresses 8 security vulnerabilities but also contains an advanced health check feature that reports back to the user on the performance of the browser.
3 of the security patches address issues surrounding memory safety and corruption, and use-after-free weaknesses. All critical patches will address vulnerabilities which if exploited could potentially lead to remote code execution.
Version 21 of the 3rd most popular browser also sees the addition of a ‘health report’ feature. The system logs basic health data from your browser, including the number of crashes, time to boot and the running time. The feature is designed to give the user a full overview of their browsing systems health and performance.
To access this ‘health report’ click the help menu within the updated Firefox browser.
