The Mozilla Foundation has released yet another update for its email client, Thunderbird 2.0.0.21, and as you’ve grown accustomed from previous releases, this update is meant to address a few security issues that affect the software application – 3 of which having been deemed as critical.

If you do not know what that means, here is a little reminder for you. Mozilla uses a 4 tier rating system when it comes to security vulnerabilities that affect their software applications: low, moderate, high, and critical. The critical rating is the highest one a vulnerability can get and it means that while you are browsing the web, said vulnerability can be used by a person with malicious intent to run attacker code or install software on your machine.

“As part of Mozilla’s ongoing security and stability update process, Thunderbird 2.0.0.21 is now available for Windows, Mac, and Linux for free download. We strongly recommend that all Thunderbird users upgrade to this latest release. If you already have Thunderbird 2.0.0.x, you will receive an automated update notification within 24 to 48 hours. This update can also be applied manually by selecting “Check for Updates…” from the Help menu,” Firefox Launch Coordinator with the Mozilla Corporation, Samuel Sidler explains.

If you are running Mozilla’s mail client on your machine and would like to stay protected from all the usual nasties one can expect to encounter online, then you are advised to update. Keeping an up-to-date and patched system is a crucial step in ensuring that you stay safe in an increasing threatscape.
