Mozilla is urging Firefox users to update their browsers before March 14, 2025, due to an expiring root certificate. Failure to update could lead to significant disruptions and security vulnerabilities, impacting add-ons, content signing, and DRM-protected media playback.
According to a Mozilla support document, the expiring root certificate is crucial for verifying signed content and add-ons across various Mozilla projects, including Firefox. Without updating to Firefox version 128 or higher (or ESR 115.13+ for Extended Support Release users, including those on older Windows and macOS systems), users could experience major issues.
Consequences of Not Updating
Failing to update Firefox before the deadline could result in several critical problems:
- Disabled Add-ons: Installed add-ons will be deactivated, limiting browser functionality and potentially disrupting workflows.
- Content Signing Issues: Problems with content verification could impact the reliability and security of websites and online services.
- DRM Playback Failure: Streaming services and other DRM-protected content may cease to function, preventing access to movies, TV shows, and other media.
- Security Risks: Users may be exposed to heightened security threats, including compromised passwords, data breaches, and unknowingly visiting malicious websites.
How to Update Firefox
Mozilla recommends checking your Firefox version by navigating to Menu > Help > About Firefox. This will display your current version and prompt you to update if necessary.
Who is Affected?
This issue impacts Firefox users on Android, Windows, Linux, and macOS. iOS users are unaffected due to a separate root certificate management system. Users of Firefox-based browsers like Waterfox, Tor, and LibreWolf should also update to the latest versions.
Additional Security Measures
Beyond updating Firefox, users can further enhance their online security by:
- Using a Password Manager: Employ a reputable password manager to create and store strong, unique passwords for all online accounts.
- Installing Antivirus Software: Utilize robust antivirus software to protect against malware and other online threats.
