I was just taking a look at the mark-js sample pages on Nightly and when I first opened the debugger the panel was completely empty. I closed the tools (keyboard shortcut didn't work) and then reopened them after refreshing and it worked. I haven't been able to reproduce this exactly yet but I wanted to log this error.
