Security News > 2020 > January > Critical Firefox 0-Day Under Active Attacks – Update Your Browser Now!
Attention! Are you using Firefox as your web browsing software on your Windows, Linux, or Mac systems?
If yes, you should immediately update your free and open-source Firefox web browser to the latest version available on Mozilla's website.
Why the urgency? Mozilla earlier today released Firefox 72.0.1 and Firefox ESR 68.4.1 versions to patch a critical zero-day vulnerability in its browsing software that an undisclosed group of hackers is actively exploiting in the wild.
Tracked as 'CVE-2019-17026,' the bug is a critical 'type confusion vulnerability' that resides in the IonMonkey just-in-time compiler of the Mozilla's JavaScript engine SpiderMonkey.
By default, automatically installs updates when they are available and activate a new version after a restart, you can always do a manual update using the built-in functionality by navigating to Menu > Help > About Mozilla Firefox.
