The Debugger panel in the Firefox Developer Edition 52.0a2 is actually an external project reworked from scratch, which doesn't have all features of the original Debugger panel yet.

The watch expressions are obviously not enabled yet due to some issues.

So, if you need watch expressions, you either need to wait until the feature is reimplemented in the new Debugger panel, or you can switch to the old UI by setting the preference devtools.debugger.new-debugger-frontend in about:config to false.
