In particular, I created a script to start Firefox which I double-click and choose 'Run in terminal,' but when the shell exits Firefox is killed immediately.

How do I prevent this from happening?

You need to put the nohup before the command that launch firefox, so it needs to looks like that:

>$ nohup firefox

Also executing bashrc in your script can set environment variables needed by Firefox or other programs. –  Garrett Hall Nov 30 '11 at 14:42
You can also use disown, a bash internal to achieve the same thing. This wont redirect output like nohup will but it can be used to orphan any long running jobs you started without the likes of nohup and you want to keep them running after you leave. –  Matthew Ife Nov 30 '11 at 18:38

Also Make sure you execute firefox as a background job and not as a front running since the shell is parent and is waiting for the firefox to run and exit before the prompt is to be returned.
