provide

(a) information on which operating system

(b) which display manager/desktop you use

(c) which web browsers you have installed and wish to use

export DISPLAY=your-X-Window-terminal's-address:0
/opt/mozilla/bin/mozilla file.html

(Substitute the PATH to your preferred browser in the above.)
