I have /usr/bin/firefox with permissions : rwxrwxrwx owner : root group : root
I am 'user' on my system. When I run firefox, and do a: ps -ef| grep firefox I find that the owner of the process is 'user'.
Now, when this firefox process tries to open a html file with permissions : ---rwxrwx owner : root group : root
should it be able to read the file?
Moreover, to render this file on the screen, does the browser need read or execute permission?
