Earlier today we were reporting that the Mozilla Foundation released the first update for the Firefox 4.0 browser. Firefox 4.0.1 is a stability and security update that is meant to make the browser a more stable and a safer platform. We now have to report that apart from the Firefox 4 browser, the Mozilla Foundation updated its Thunderbird email client as well.

The update, Thunderbird 3.1.10, is a security and stability update as well. It was released on the 28th of April, the same date that Firefox 4.0.1 was released.

“Thunderbird 3.1.10 is now available for Windows, Mac, and Linux for free download,” announced Mark Banner. “This release makes several improvements to Thunderbird’s performance, stability and security. We strongly recommend that all Thunderbird users upgrade to this release.”

Thunderbird 3.1 users will be presented with an automated update prompt in the 24 to 48 hours following the release of the update. If you did not receive an automatic update prompt, you can manually trigger an update by clicking Check for Updates from the Help menu.

The security advisory page for Firefox 4.0.1 said that the update comes with 3 security advisories, two of which carrying the critical rating. Mozilla give the critical rating to vulnerabilities that can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.

The security advisory page for Thunderbird 3.1.10 doesn’t say a thing – I assume it hasn’t been updated yet. According to Bugzilla though, Thunderbird 3.1.10 comes with a fix for more than 71 bugs, out of which 2 got the highest rating blocker and 16 are rated as critical. We will know more about the security problems Firefox 3.1.10 fixes when Mozilla updates the security advisory page.

In related news, Mozilla recently announced it will open a new office in San Francisco. The new office will be in the same building where Google keeps a well-staffed office – Hills Plaza in downtown San Francisco.
