Install Firefox 12 in 5 easy steps
1. Download
Download the release from the official channels page:www.mozilla.com/firefox/channels/
A 64 bit build is also available in the x86_64 directory of Mozilla's FTP.
This how-to supposes that the downloaded file is saved in the “Downloads” directory situated in your home directory.
2. Extract
The downloaded file is a compressed .tar.bz2 archive. In case you want to Learn more on these extensions: tar, bzip2. To extract this juicy archive, open the Downloads directory. Look for a file named firefox-12.0.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-12.0.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 firefox-12.0.tar.bz2 archive can now be deleted.
3. Move to /opt
External programs like LibreOffice, Google Chrome, Adobe reader, ... are all installed in the /opt directory. If you want more info about why /opt, check out these two links:Where to install my products on linux?

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

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