Debugging in Firefox

I'd be grateful for some pointers/suggestions about how best to debug a userscript using Firefox's built-in tools. (Or suggestion that I should get some other extension, if necessary.)

console.log()
console.trace()

I'm only a novice developer but I find that http://www.dirtymarkup.com/ can be very useful for debugging and cleaning up scripts.

Also JSBIN works wonder for troubleshooting.
