I'm trying to figure out how to debug greasemonkey script using firebug. It works on my laptop but I can't get it to work on my pc. Both have the same versions of Windows, Firefox and firebug. On my laptop when loading a page with associated GM scripts then go into firebug, all of the GM scripts are listed under the scripts tab and I can add break points and debug them. However on my PC on the same webpage the GM scripts don't appear in the list under the scripts tab. Working on my laptop is difficult because it's slow and has a small screen so I'm very keen to get this working on my pc. Any suggestions on how to sort this would be greatly appreciated. screenshots:- https://plus.google.com/u/0/photos/100778011860893013170/albums/5926837021137009345?partnerid=gplp0
