Mozilla released Firefox 67.0.3 on June 18, 2019, to fix a critical security vulnerability detected in exploits in the wild. Firefox is a free web browser application developed by the Mozilla Foundation. It installs on desktop and laptop computers running Windows, MacOS and Linux operating systems. Mobile Firefox versions exist for both Android and iOS devices. We recommend updating your Firefox installation as soon as possible.
According to Mozilla Security Advisory 2019-18, Samuel Groß of Google Project Zero, and Coinbase Security reported the vulnerability (CVE-2019-11707):
A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in
Array.pop. This can allow for an exploitable crash. We are aware of targeted attacks in the wild abusing this flaw.
Firefox is known for private browsing, tracking protection, and faster page loading. With Private Browsing, the browser blocks online trackers and clears your search and browsing history when you’re done. Built-in tracking protection blocks third-party content that tracks you as you surf the web. The performance benefit of tracking protection is up to 44% faster page load times.
Firefox is highly customizable with thousands of extensions, themes, and a drag-and-drop toolbar. With a Firefox account, users have the option to sync settings, passwords, and bookmarks across all of their devices. Multi-account containers are unique to Firefox so users can separate their personal, work and shopping browsing without the need to log out of accounts or switch browsers. With up to 30% less memory usage than Chrome, Firefox is fast — very fast.
