Sure. Still a good place to start if you are looking to trial the idea.
Continuing to think "inside the box" of built-in Firefox tools you could pair it with different windows in different profiles, train yourself to open the "addictive" sites only in the throttled profile. I don't have the Containers add-in installed, but I wonder if you can throttle Containers separately (and if not, might be an interesting feature request).
