You Need to Update This Popular Browser Before It Becomes a Security Risk
1 min read
Summary
Firefox users must update their browser immediately or face the loss of essential security updates, warns Mozilla.
Already on 14 March 2025, a critical root certificate will expire, leaving any users who have not updated their systems vulnerable.
The certificate is used to verify the authenticity of websites, add-ons and software; without it, these security functionalities will break.
To ensure an unaffected service, users must update to the latest version of Firefox, version 128 or above, or Firefox Extended Support Release, version 115.13 or above.
Failing to update could result in exposure to malicious add-ons, untrusted certificates and compromised passwords.
Users are urged to check regularly that they are running the latest available browser version to prevent security breaches.
