This profile does not allow the Parole media player to play a .MOV file directly from Firefox. Instead it suggests that the file be first downloaded. But I noticed that the file is stored in /tmp regardless. So I thought that maybe commenting out lines 42 and 44 may solve the problem, but I'm a n00b and don't want to screw anything up. So I'm asking for suggestions on how I can modify this profile, or maybe even install a new firefox profile so that Parole is able to play directly from the browser.
