Firefox Quantum 58.0 plugins for WebSocket parsing?

Question

Mozilla Firefox

Tell me if there are plugins for WebSocket analysis for Firefox Quantum 58.0?
So that you can see what data is transmitted in both directions, etc.
By standard means, you can only view a request to open a connection and that's it.

Answer 1

No way, work on supporting WebSocket in the Firebug console is still underway ( thread on github ).
PS The current version with ESR is 60, it's also the first one for Quantum, it's time to move on.
