Cool add-on, how can I use style sheet?
I'm using a dark Firefox theme, I can't see the output as expected...

This review is for a previous version of the add-on (0.17.4).

Using style sheet is broken in the original version since FF 22+. I've already fixed it for the next version but haven't styled it nicely yet. I'll probably release an update in the next week or so.
