I have written this before in my old post, but I could not find it.
By default chromium-browser does not allow root to launch, you need to be a non-root user in order to launch chromium-browser, this works the same for google-chrome.
first find the filename chromium-browser:
find / -type f -name chromium-browser
This is one of the location of chromium-browser, however this is the file we need to hack using hexedit program.
If you do not have hexedit installed, use apt-get install hexedit.
hexedit will jump to the keyword, change geteuid to getppid. Then save by pressing ctrl+x, then press y to save.
People who used backtrack-linux distribution may prefer chromium to firefox, as backtrack linux tools need root privilege it is preferred to be used as root instead of non-root user account. Chromium has good security like sandboxing hence it is a good browser to choose.
