$ wget https://download-installer.cdn.mozilla.net/pub/firefox/releases/47.0/linux-i686/en-US/firefox-47.0.tar.bz2
$ wget https://download-installer.cdn.mozilla.net/pub/firefox/releases/47.0/linux-x86_64/en-US/firefox-47.0.tar.bz2
After downloading, extract it to a desired directory.
$ tar xvf firefox-47.0.tar.bz2
Next, move to extracted directory.
$ cd firefox
Now, check the version of already installed Firefox and get the extract location of binary command.
$ firefox -V Mozilla Firefox 46.0
$ which firefox /usr/bin/firefox
Now, you have two options, one you can remove existing version and another, if you want to keep both versions. Here, we are keeping two versions. So, I'll rename existing version and link original one to new instance.
Note: Make sure to execute following commands as a root user or a user with sudo privileges.
# mv /usr/bin/firefox /usr/bin/firefox-old # ln -s /full-path/firefox/firefox /usr/bin/firefox OR $ sudo mv /usr/bin/firefox /usr/bin/firefox-old $ sudo ln -s /full-path/firefox/firefox /usr/bin/firefox
Finally, verify the newly installed Firefox and launch it from command-line or from taskbar as normal user.
$ /usr/bin/firefox $ firefox -V Mozilla Firefox 47.0
