Just a piece of input: I just tested on my computer, Firefox 40.0.3 (my 
god how they are incrementing that version number!) and Linux, and I had 
no problem navigating the frame view when reading a local file. So maybe 
it's a Windows thing. You mentioned cygwin. Can you check if there seems 
to be any file permission issues with the webrev files?
