Chrome - blackbox a script - no menu item

Question

I'm trying to blackbox a script (as mentioned here https://developer.chrome.com/devtools/docs/blackboxing ) but I don't see that as an option when I right click on the file in the left hand Sources panel (Navigator).

Nor do I see any mention of it in Settings.

Any suggestions?

I'm using

Google Chrome   48.0.2540.0 (Official Build) canary (64-bit)
Revision    37d6b63597f41322f6092405ae913b19a7e85686-refs/heads/master@{#354704}

Answer 1

Right-click WITHIN the editor of the script that you want to blackbox, and NO LONGER on the actual file name in the navigator panel. The option is on the bottom of "that" context menu. (image below)

I know this is a bit old and was just about to add a comment that I couldn't find it either, but I lucked out. Using Chrome Version 50.0.2661.102 m. Hope this helps.
