Iceweasel and Icedove on Debian 7.0 “Wheezy” : How to keep them up to date

As you may know, Iceweasel is the equivelent of Firefox and Icedove is the same as Thunderbird, on Debian Systems.

Firefox and Thunderbirds are open-source projects, so there is no problem with using it, but because of some licence issues in the past, from Debian Lenny (I think), the Mozilla programs got the 2 different names and logos.

You have to do a few tweaks if you want to keep up to date Iceweasel and Icedove on Debian Systems.

Step 1: Add this line to /etc/apt/sources.list.d /iceweasel.list:

$ sudo echo ‘deb http://cdn.debian.net/debian experimental main’ > /etc/apt/sources.list.d/iceweasel.list

Step 2: Download and install the authentification key:

$ wget -c http://mozilla.debian.net/pkg-mozilla-archive-keyring_1.1_all.deb
$ sudo dpkg -i pkg-mozilla-archive-keyring_1.1_all.deb && rm pkg-mozilla-archive-keyring_1.1_all.deb

Step 3: Update the repo index:

$ sudo apt-get update

Step 4: Install the latest versions of Iceweasel and Icedove:

$ sudo apt-get install -t experimental iceweasel
$ sudo apt-get install -t unstable icedove

This is it. Now you can update Iceweasel and Icedove successfully.
