Installing Firefox 3.5 in Ubuntu (Probably the better way )

1. Add the following line to /etc/apt/sources.list
deb http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu jaunty main

2. Identification key for this repository (Applications -->Accessories --> Terminal)

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 247510BE

3. Refresh your system cache:

sudo apt-get update

4. Setup this package, latex-xft-fonts and also firefox-3.5-gnome-support

sudo apt-get install firefox-3.5 firefox-3.5-gnome-support latex-xft-fonts

5.

sudo su

cd /usr/bin

ls -l firefox*


The ls -l is the command for listing in long and detailed format the files and directories


6. after the last line is entered the follow will appear in the terminal

lrwxrwxrwx 1 root root 11 2009-07-04 16:22 firefox -> firefox-3.5
lrwxrwxrwx 1 root root 32 2009-06-27 21:08 firefox-3.0 -> ../lib/firefox-3.0.11/firefox.sh
lrwxrwxrwx 1 root root 34 2009-07-04 16:19 firefox-3.5 -> ../lib/firefox-3.5.1pre/firefox.sh

7. Time to enjoy Firefox 3.5

Firefox will now be updated through the Ubuntu Package Manager from now on.
