I just installed Firefox Developer Edition (V 52.0a2 (2017-01-03) (32-bit)). I tried to debug the JS file and as usual hovered over the JS variable. I was expecting a pop to appear with a quick watch but nothing appeared. Then I tried to right click the variable and expected a context menu with option to add variable to the watch but that is also not there, instead I got two options "Remove Breakpoint", "Edit Breakpoint". All these things were working in older versions of FF Developer edition. What I am missing here or they simply removed "add to watch" option (which I don't think so for all valid reasons.)
Firefox Developer Edition not showing quick watch pop up window when hovered over variable

What you are seeing is a new debugger UI developed independently from Firefox, which implements new features but is still missing some of the features of the old UI.
The watch expression features (and with them the context menu option) were obviously already reimplemented, but not merged into the Firefox sources yet. See also bug 1319402.
