How to Install Firefox 15 on Ubuntu

Mozilla Firefox 15.0 can be installed in the following Ubuntu operating systems: Ubuntu 12.04 LTS (Precise Pangolin), Ubuntu 11.10 (Oneiric Ocelot), Ubuntu 11.04 (Natty Narwhal) and Ubuntu 10.04 LTS (Lucid Lynx).

step 1)

No matter what Ubuntu operating system (see above supported OSes) you are running, open a terminal and paste the following command:

sudo add-apt-repository ppa:mozillateam/firefox-stable

Hit the Enter key, type your password when asked and hit the Enter key. Hit Enter again when asked.

Don't close the terminal window! Proceed to the next step.

step 2)

Now paste the following command in the same terminal window:

sudo apt-get update && sudo apt-get install -y firefox

Your current Firefox installation will be overwritten. Wait for the installation to finish and close the terminal window.
That's it! The new Mozilla Firefox 15.0 is now fully installed in your Ubuntu machine. You'll need to restart Firefox for the changes to take effect.
In time, your Mozilla Firefox web browser will automatically upgrade to newer versions, so make sure you update your system regularly.

New Kernel Vulnerabilities Affect Ubuntu 12.04

Canonical announced a few hours ago, June 13th, in a security notice, that a new Linux kernel update for its Ubuntu 12.04 LTS (Precise Pangolin) operating system is now available, fixing six security vulnerabilities discovered in the Linux kernel packages by various developers.

These are the six kernel vulnerabilities found in the kernel packages for Ubuntu 12.04 LTS: CVE-2012-2121, CVE-2012-2133, CVE-2012-2313, CVE-2012-2319, CVE-2012-2383, and CVE-2012-2384.

As usual, you can click on each one to see how it affects your system, or go here for in-depth descriptions, as it affects other Linux operating systems as well.

The security flaws can be fixed if you upgrade your system(s) to the linux-image-3.2.0-25 (3.2.0-25.40) package(s). To apply the update, run the Update Manager application.

Don't forget to reboot your computer after the upgrade!

ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules which work with the new Linux kernel version.
