Do not base usage off of this review, as I have not tried the extension. I read the "about this extension" description, and the extension seemed to be a digital "tattletale" or "gàomìzhě"(I think). I just couldn't believe we have now crossed into digital territory to become "hall monitors", those children who wanted to be bullies, but their body shape would not allow them to become a bully. Now we have this? A digital wannabe bully? Or maybe I am just misunderstanding this extension?
