14 DAY TRIAL // The Ubuntu maintainers for Firefox have finally released the latest 39.x branch of the Internet browser for users of Ubuntu 12.04 LTS.
Ubuntu 12.04 LTS is still supported by Canonical until 2017, so it would have been weird for the users of this distro to be stuck with an older version of the application. The maintainers have finally pushed the Firefox 39.x update to the repos, a few days after it had already been released for all the other supported distros in the Ubuntu family.
The funny thing is that the new version of Thunderbird hasn't landed in the Ubuntu repos and it's been out for quite some time now. In any case, lots of vulnerabilities have been closed in this new release and we've already covered what the new features are.
For a complete list of changes, you should check the security notice. The affected platform is Ubuntu 12.04 LTS. To get this, you can simply run the Update Manager application, but you can also use the terminal.
Open a terminal and enter the following commands (you will need to be root and you will need Internet access):
sudo apt-get dist-upgrade
