Debugging greasemonkey-like scripts

Solution
I've created an interactive console for debugging Greasemonkey scripts. It requires Google Gears, but it includes a persistent history of commands that were typed.
UPDATE: Here's a link to a blog post describing using GreasyThug to debug a GM script. It's got a step by step procedure to replicate an error and devise a solution.
Problem
I'm writing javascript code that is read in as a string and executed via eval() by a firefox extension. Firebug does "see" my script so I am not able to use breakpoints, see objects, etc. I am currently using Firefox's error console which I'm starting to find limiting. What are my other options? Ideally, I would be able to use Firebug or something similar to it. How do people generally debug Greasemonkey scripts? I've tried using Lint and other validators, but my script uses a lot of objects and functions provided by the extension environment, making of a lot of the errors reported irrelevant. Also, the output tends to be too nitpicky (focusing of spacing issues, etc).
