Firefox Developer Edition - Developer tools need Media queries toogle bar in Responsive Design View

[Krishnaprasad]

It would be useful to display media queries in a similar way to Chrome using the toogle bar and device frame. It really speeds up development, well it does for me, to be able to see any quickly toggle between them.

Is that similar to Firefox's Responsive Design Mode? See: https://firefox-source-docs.mozilla.org/devtools-user/responsive_design_mode/

I'm not sure whether this button appears by default or whether I turned it on in the settings:

Or perhaps the question is, how can RDM be improved?
