I see what I did to jump to the debugger window, it was by unticking (not ticking) the show original sources tab. But I think that always jumping there is more consistent whether it's ticked or not.
I can confirm this. I do a lot of development with Meteor and CoffeScript, and clicking a link to a source file opens a new window. (Then there's the fact that Meteor errors are logged in a horrible format, but that's a Meteor problem, in fact what I'm working on right now.)
Apropos, the functionality in question was added via #766001, in case someone wants to check the leading discussion.
