If you are using Mozilla’s Firefox web browser on PC, you should update it to the latest version right now. Mozilla has released security updates Firefox 67.0.3 and Firefox ESR 60.7.1 to fix a critical bug that hackers could exploit to take control of your PC.
Essentially, attackers could potentially deceive users of unpatched Firefox versions into visiting a maliciously crafted web page and, subsequently, executing arbitrary code on their systems.
The US Cybersecurity and Infrastructure Security Agency also issued an alert, encouraging users and administrators to review the Mozilla Security Advisory for Firefox 67.0.3 and Firefox ESR 60.7.1 and apply the necessary updates.
