What steps will reproduce the problem? 1. /Applications/Firefox.app won't work 2. /Applications/Firefox.app/Contents/MacOS/firefox-bin only allows one instance, conflicts with GUI launched Firefox.app

Please provide any additional information below.

I got the ShowOnMap tool working by using this as my default browser: open -a /Applications/Safari.app/

Since the dialog doesn't recognize OS X style apps.

Safari works nicer than Firefox.app since Firefox won't load in a new tab and insists on starting a new browser session. This forces you to close your currently open brower with each launch. Safari works better and creates a new tab for each instance.
