Too much effort to make it work and even then copying selectors didn't work. Avoid unless you want to waste your time.

Works pretty well for youtube! Cant seem to make it work for disqus messages tho. cant find a way to select any of it, it does not highlight to blue when I type a valid selector

Very good :)
