Mozilla has released updates for two of its products, mainly the Firefox browser and the Thunderbird email client. The updates in question are Firefox version 3.6.7 and Thunderbird version 3.1.1; for Thunderbird users who are on the older 3.0 version, Mozilla has rolled out Thunderbird 3.0.6. These updates are meant to make Firefox and Thunderbird more stable and safer.

Speaking of making things safer, it must be said that Firefox 3.6.7 for example comes with fixes for a grand total of 14 security vulnerabilities. The better part of them have been given the highest severity rating – 8 vulnerabilities that Firefox 3.6.7 fixes carry the critical rating. The remaining vulnerabilities are divided as follows: 2 are rated as high, 4 are rated as moderate. Additional details about these vulnerabilities are available here.


For security reasons you are very well advised to get Firefox 3.6.7. An automated update prompt will be shown to users who are already using Firefox 3.6.X. If you want to update right now, you can manually get the latest version by clicking Help -> Check for Updates. Or you can download Firefox 3.6.7 – there's a download link at the bottom.

Moving on to Thunderbird, we know that Thunderbird 3.1.1 as well as 3.0.6 come with “several fixes to improve stability and security” – we have no idea how many security fixes there are though because the security advisories were not updated at the time of writing this. We’ll go with Mozilla here who strongly recommends that users upgrade to the latest Thunderbird version.

Just like with Firefox, Thunderbird users should get an automated update notification, but they can also manually get the latest version by clicking Help -> Check for Updates. Or you can just click the download link at the bottom of this article.

If you would like to get Firefox 3.6.7, you can download the browser here. Don’t forget to check out the release notes.
If you would like to get Thunderbird 3.1.1, you can download it here. Thunderbird 3.0.6 is available here. Don’t forget to check out the release notes for v. 3.1.1 and for v. 3.0.6.
