To install the Firefox 15.0 web browser from a .tar.bz2 archive file on a Linux system, you can follow these steps:
Download the Firefox 15.0 .tar.bz2 archive file from the Mozilla website or from a mirror site.
Extract the contents of the .tar.bz2 archive file to a directory on your system. You can use the tar command to extract the archive file. For example:
tar -xjf firefox-15.0.tar.bz2
This will extract the contents of the .tar.bz2 archive file to a directory with the same name as the archive file (e.g. firefox-15.0).
cd firefox-15.0
./firefox script to start Firefox../firefox
Alternatively, you can create a symbolic link to the firefox script in a directory that is included in your PATH environment variable. For example:
ln -s /path/to/firefox-15.0/firefox /usr/local/bin/firefox
This will allow you to start Firefox from any directory by simply running the firefox command.
You can find more information about using the tar command and its options in the documentation for your Linux distribution or by running the tar --help command.
Keep in mind that installing software from a .tar.bz2 archive file may require a certain level of knowledge and experience with Linux systems. You may need to consult the documentation or seek assistance from an experienced administrator if you encounter any difficulties.
You can find more information about using Firefox on Linux systems in the Firefox documentation or by searching online.
