Firefox users are urged to update their browser to either version 128 or ESR 115.13+ by March 14, 2025, to prevent issues related to add-ons and protected content playback. This is because a root certificate that is crucial for verifying signed extensions, digital signatures, and other browser functionalities will expire on that day. Failure to install the update on time could result in disruptions to add-ons, remote updates, and DRM content mechanisms.
The update is essential for all Firefox users across Windows, MacOS, Linux, and Android platforms. Without the update, existing add-ons may become disconnected, and protected media files, such as streaming videos, may fail to play.
The root certificate plays a vital role in authenticating websites, add-ons, and software updates. When its validity lapses, the browser loses its ability to verify the authenticity of these elements, potentially causing functionality issues. Firefox 128 and ESR 115.13+ introduce a new certificate to mitigate these problems and ensure smooth browser operation.
To check the browser version on a PC, users can navigate to the Firefox menu, select “Help,” and click on “About Firefox” to view the current version and verify the presence of updates automatically. Android users can check their version by accessing the settings menu and selecting the “About Firefox” section. If prompted to update, it indicates an outdated version. iOS users do not require browser updates.
It is important to note that updating to the latest version of Firefox will not impact saved bookmarks, passwords, or settings. However, it is recommended to enable synchronization through a Mozilla account as a precaution to ensure all data is securely stored before updating.
Failure to update Firefox may result in add-on malfunctions, inability to play DRM content, and website issues. Moreover, not updating could pose serious security risks, including vulnerabilities to malicious add-ons, improper verification of digital certificates, and the inability to receive notifications of compromised passwords.
