1. Launch Firefox.
2. Access the about:support page and observe the "Enterprise Policies" information.
3. Access the about:policies page (available in Fx 64 and Fx 63).

I'd love to give this a go, but haven't done any work with firefox.

I have replicated the problem with the attached json file, and I realize this is a silly question, but what do I need to install to try and help fix this? 

Go through the Building Firefox on Windows (I'm on Windows 10, 64bit) to start? (https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Windows_Prerequisites)

Hello there, thanks for volunteering!

Yeah, you should go through the Build instructions. Since for this bug you won't need to work on any C++ code (only JS), I suggest that you set up your builds using artifact builds (https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Artifact_builds) because they will be much faster to work with (they use precompiled binaries and only repackages the JS/CSS files that were changed)
Hi Felipe, I believe this bug is narrow enough in scope to take on as a newbie. Would you say this is a GFB? if so I'd like to give it a try!
I already have a build of Firefox so I'll attempt to fix it straight away.
Hello Pablo, there's already a volunteer looking at this bug, but there are plenty others to take a look. I'm gonna suggest two in the Enterprise Policies component that are highly desired and would be awesome for someone to work on: bug 1502134 and bug 1485193.

(the first one that I mentioned is narrower, so it's a good starting point!)

Sorry, I got bogged down trying to find a job (fun fun fun), if you want to assign it to someone else, I completely understand, otherwise I will try to get to it asap (maybe a week or so at least).
Ok, no problem! I'll leave the bug unassigned in case someone else wants to take it. If you want to contribute later you can always see if this bug is still open or choose a new one :)

The problem here was that the new test was added in browser.ini in the spot from the `skip-if` settings of another test that is only supposed to run on mac:

Is this something we should consider for backport?
Yeah, I guess this is simple and it helps people to debug policies problems

This grafts cleanly to ESR60 also - should we take it there too?
Flags: needinfo?(felipc)
On one hand, about:policies is not present on ESR, so it's not gonna be highly visible.. On the other hand, this will still spew the error message to the console, and say that Enterprise Policies is in a "Failed" state in about:support.. So I think it will in general be useful for ESR.
