I am on a MacOS Firefox v79.0 16 bit and I used to have the Params tab in the Network section of the Developer Tools that shows the GET/POST parameters.

It suddenly went missing after some update this year. May I know how can I get it back?

The Request panel shown in your screenshot shows POST params for me on my test login page (just put any text for the credentials):

If there are some cases where it doesn't work, I suggest alerting the DevTools team on their forum over here:

It does not seem to show GET parameters, which would be useful.

Thanks for the response. I have narrowed down the issue. I'm using a service worker and it seems that Firefox does not show the POST (formdata) parameters for cached pages, which should not be the case since POST data cannot be cached. Chrome shows the parameters regardless of the service worker and I think that should be the expected behavior.

Posting a follow up in case anybody else encounters this and searches for a solution. Mozilla's dev team has responded that it is a bug and they are in the process of fixing it.
