I really dislike getting screen-shots in the format of power-point files. Thankfully, 10.5′s Quick Look can help me preview power-point files. What I needed was a way to have Firefox automatically Quick Look all power-point files that I downloaded. Here’s how to do it:
Open up Script Editor and paste this:
on open filelist repeat with i in filelist do shell script "qlmanage -p '" & POSIX path of i & "' >& /dev/null &" end repeat end open
File > Save As…. Choose “Application” and save it somewhere it won’t move. I choose /Applications/ql.app.
Now simply choose ql.app next time you download a power-point file or set it up in Firefox’s Preferences > Applications.
qlmanage is the command-line tool to open files in Quick Look. By using AppleScript you are able to create this thin “application” that Firefox will trust and give a downloaded file (As opposed to a shell script, which Firefox will not let you choose as a file handler).
