Canonical has just announced that Firefox 40.0 is now available in the official repositories for Ubuntu 15.04. Ubuntu 14.04 LTS, and Ubuntu 12.04 LTS.

The Ubuntu maintainers have been very quick to integrate Firefox 40.0 in the repositories, together with all the new features that have been implemented in the latest version of the browser from Mozilla. Usually, it takes a few days until maintainers get Firefox in the official repos, but it looks like they are doing a lot better now.

All of the updates made to Firefox in the past few months have been integrated much more quickly, and that is a very good thing indeed.

"Gary Kwong, Christian Holler, Byron Campen, Tyson Smith, Bobby Holley, Chris Coulson, and Eric Rahm discovered multiple memory safety issues in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox," reads the security notice from Canonical.

This is just one of the security issues that have been corrected in Firefox 40.0. For a more detailed description of the changes and features in the new version, you should check out our original report. In any case, if you want to get Mozilla Firefox 40.0, you just have to upgrade the system and you're golden.

Please make sure that you restart the browser after the upgrade has been completed. Enjoy!
