Firefox 3.6 for Ubuntu 9.10 Karmic

This news is a bit old, but Firefox 3.6 is out now. For Ubuntu 9.10 Karmic, this new version is not in the official repositories yet. Here is a way to install it for yourself.

For those who don't like to download and run the files straight from the getfirefox.com website, here is an apt repository for Ubuntu which works well.

The group's website is here: https://launchpad.net/~mozillateam/+archive/firefox-stable

They have instructions there for adding this software repo to your system, but basically you do the follow.

1) Close down Firefox completely. This includes all download and add-on windows.

2) Add these lines to your apt-sources list. You can do this by editing the file /etc/apt/sources.list or adding them through whatever graphical package manager you use (such as KPackageKit or Synaptic).

# Firefox Stable Channel Packages
deb http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu karmic main
deb-src http://ppa.launchpad.net/mozillateam/firefox-stable/ubuntu karmic main

3) Add the repositories apt-authentication keys to your system, and thus help prevent man-in-the-middle attacks. Running this command on a console will do it for you.

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com CE49EC21

4) Refresh/Update your apt lists. (This downloads the newly listed software). You can install it by using whatever graphical package manager you use (such as KPackageKit or Synaptic) or from a console with this command:

sudo apt-get update

5) Install the program Firefox. Not firefox-3.6 (which won't really give you anything). You can install it by using whatever graphical package manager you use (such as KPackageKit or Synaptic) or from a console with this command:

sudo apt-get install firefox

There. You are done. Under KDE, you should be able to just click the firefox icon in the apps menu and in all Linux system you should be able to just run the command 'firefox' to load the browser. Happy browsing.
