Firefox 4 (stable) was released yesterday (March 22 , 2011), So I decided to write an article on how to install firefox 4 on Ubuntu the easy way.
Now if you goto mozilla.com to download the latest version on linux you prompted to download a file called firefox-4.0.tar.bz2
but many people don’t know how install this file , well the easier method is to download the latest version from Firefox stable PPA
but before you do this make sure to uninstall any beta versions.
Open terminal and type the following commands
First thing to do is add the Firefox stable PPA
sudo add-apt-repository ppa:mozillateam/firefox-stable
then before we can install firefox we need to update the PPA
sudo apt-get update
Finally we can install Firefox
sudo apt-get install firefox
And thats it , firefox will now download and install itself , Simple and Easy !
I found a way to run Firefox 4 Beta and Firefox 3 simultaneously .
