Facebook Publishing Tools empty when viewed in Firefox[Mac.]

[HCSelf71]

Hello,

I am unable to view the Publishing Tools information when working on a page for which I am an admin. I CAN see the Publishing Tools info when I view that tab through Safari and Chrome.

Steps I have tried to resolve the issue, which did not work:

1) I have tried clearing my history and cookies.

2) Uninstalling and reinstalling Firefox.

Yes, I have rights to view Publishing Tools as I'm an admin, and, as said above, I can view that page correctly in two different browsers.

I am using Firefox 58.0.2 on my MacBook pro, El Capitan.

Thank you for your assistance!

Facebook's info on this issue is scant and is centered only on clearing cookies and history.

This issue has persisted over the last year and through all Firefox updates issued during that time.

Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

I have the same problem in Firefox but not in Chrome or Safari. I have tried Safe Mode with no success, and I have tried creating a new profile with no success.

Any other suggestions? Anyone else solve this?

Thanks.

This morning, all of a sudden and for no obvious reason, Facebook's Publishing Tools are now visible in Firefox. My assumption is that Facebook changed something on their end that fixed this - and we wil never know what.
