Es efectivo, logra analizar el sitio y ayuda a no depender tanto de PageSpeed Insight. Para quienes dicen que falla con sitios locales, es lógico ya que tiene que acceder a través de la internet y no en redes locales.

This does everything is says it'll do perfectly. However, I did not realize what the intention of this plugin is. I was hoping to get the Chrome DevTools experience in Firefox, but instead all this plugin is is a shortcut to PSI, which is okay I guess, but who really needs a plugin for a shortcut? Not faulting the devs for this, they work really hard, and Lighthouse in Chrome is out of this world, and if Lighthouse would take more than a few devs to maintain in Firefox, I can't blame Google for deciding it's not worth the effort.

Four stars holding out the hope Firefox can a get a true lighthouse experience, and if not what's the point of an extension that's nearly fancy bookmarks? I love Chrome and all their developer tools!
