I use symbolic links and program shortcuts as a way to easily open different Firefox profiles ie. one for casual/personal use and another for work. This works well, but I get the "Firefox is already running, but is not responding" error message if I try to open external links with FF as my default browser. FF is actually open and running fine, but I guess it doesn't acknowledge this fact because of how I'm originally starting the process. I wasn't able to add the symbolically linked executables to the default program pane. Is there a way to bypass this error or other way to fix this? The solution to the question linked below is what I'm using to open the different FF profiles. http://superuser.com/questions/255312/pin-same-app-multiple-times-in-windows-7
