How to install Firefox in Linux

 Install Firefox in few easy steps

1.       Download

Download Firefox from Firefox.com for Linux Operating system.

2.       Extract

The downloaded file is a compressed .bz2 archive.

GUi Mode: To extract this  archive file, open the Downloads directory. Look for a file named firefox-xxxxx.tar.bz2, right-click on it and select "extract here".

Alternatively, you can extract the archive from the command line:

cd ~/Downloads/

tar xjf firefox-xx.x.x.tar.bz2

For those interested, here are the tar arguments used in the command:

x : eXtract

j : deal with bzipped file

f : read from a file (rather than a tape device)

The tar.bz2 archive can now be deleted.

3.       Move to /opt

If you already had a previous Firefox version installed in the /opt directory, remove it with the following command:

 rm -r /opt/firefox

Now move the firefox directory – which was created in your Downloads folder during extraction – to /opt:

 mv firefox /opt/firefoxx

4.       Set up symbolic links

Depending on you usage pattern, follow the instructions for case 1 OR for case 2.

Case 1: you want to use Firefox 10 as you default browser:

"Backup" the old Firefox launcher:

mv /usr/bin/firefox /usr/bin/firefox-old

Create a symbolic link pointing to the new Firefox version:

 ln -s /opt/firefox10/firefox /usr/bin/firefox

No need to update your icons/shortcuts, they should now launch the new version of Firefox.

Your old Firefox version is still installed. If you want to use it, run firefox-old in a terminal or create shortcuts/icons referring to firefox-old.
