[Project_owners] run Shell Script on Mac with nsIProcess

[Didier Ernotte]

Did you try to troubleshout your code a bit ?
Is the gjtemp.sh file created after your have run your code ?
Does FF have authority to write a file in that location ?
Does FF have authority to create a .out file in that location ?
