With the Firefox 65 release, Mozilla enhanced the security of its open-source web browser on Linux platforms by enabling “Stack smashing” protection by default, which could allow malicious actors to take control or corrupt a vulnerable program. The “Stack smashing” protection is also enabled for Android and macOS platforms. Apart from the stronger “Stack Smashing” protection, the Firefox 65 release also enhances the tracking protection by offering users stricter, custom, and standard options for controlling online trackers through a revamped Content Blocking section shown in the site information panel.
