This Alfred workflow lets you select any Firefox profiles found in ~/Library/Application\ Support/Firefox/Profiles/. It lets you open different FF profiles in parallel. This workflow is written in Ruby which I never worked with before. I think there are better ways to do it. Anyways, I am using it on a daily base.

It is not yet on packal as I am new to the community.
Any suggestions and contributions are very welcome.
