What's the correct way to take an action right before a JS-implemented
XPCOM object that acts as the implementation for a WebIDL interface
gets garbage collected?

Taking action soon after GC would work for me as well.
I'm thinking of int

Does that mean your action doesn't depend on which exact JS object got
collected,

The action is decrementing a counter on the inner window, so it's
sufficient if the C++ destructor knows if it needs to decrement the
counter and knows which window.
