The message itself comes from the start script. It checks if the current user has the id 0 (which is the root user) and exits with the message:
The Tor Browser Bundle should not be run as root. Exiting.
In general it is considered good security practise that one should not run software as root. Especially when one browses the web there are quite some possible attacks and browsers have lots of weaknesses. So if it is possible for a website to successful attack the browser, it can access local data. In the case of a root user this means that the attacker has access to the whole system. The attacker can read and write arbitrary files.
So for security reasons it is better to run software as a normal user.
But also when you think about normal operation it is quite dangerous to do everything as root. Usually people make mistakes and making a mistake as root can have catastrophic outcomes. So it is better to only make administrative work as root and everything else as normal user.
for fix this error , follow this command go to this folder /tor-browser_en-US/Browser command :
# nano start-tor-browser
in editor , find this code : " The Tor Browser Bundle should not be run as root " remove exit 1 and complain "The Tor Browser Bundle should not be run as root. Exiting." and press Ctrl + X > Y next type start-tor-browser in command line
