Expansion to highlight the author's comments in posts Habrahabra

Today I read a comment in some article that there is not enough highlighting of the author’s comments, and decided to make a plugin like that. Maybe someone will come in handy.

View on github
CRX file

UPD:
Thanks to user crea7or , added user scripts, look here . I checked it in FF 5 - it works, in Opera, unfortunately, I cannot check it now.
