Is there a way (or extension) to see WHICH TABS Are using the most energy?
Using the Activity Monitor, I see which apps are using the most RAM, CPU and energy usage- but is there a method to identify WHICH TABS are using the mos resources?

There is the Firefox Task Manager (under Tools > Browser tools in the menu bar or something similar in the application menu OR about:performance).

about:performance is also listed in about:about
See also the about:processes and about:unloads pages.
