We are looking into that right now actually to make that easier, maybe you could file a specific bug. Are you using the iframe-picker in Firefox and that isn't working as expected?

Does it work for you? Your comment seems to suggest it mostly works fine for you but for me. For me it's 100% unusable.

1. JSFiddle. Run a fiddle with a loop (setTimeout/setInterval/requestAnimationFrame). Try to find it in the debugger. Fail

2. Add a `debugger` statement in the loop. Watch as Firefox doesn't display the code in the debugger

3. Add a syntax error, see message in console, click link to code, firefox doesn't display code.
