I can confirm that it happens also in Ubuntu 16.04 51.0.1 (64-bit). I found out that in my case POST params are hidden in collapsed panel with invisible label. When you click below JSON the list will show up.

Hi tomasz@ I also see it expands if you click in the hidden element. Thanks for the info. It seems like a bad style applied to the expander

Post requests for forms work as expected, the issue with JSON will be fixed in Firefox 52, scheduled for release on 2017-03-07.
