Works great!! Rated 4 out of 5 stars

@Wlakom: Did you install Grease Monkey too?

@steeev+: Thank you so much!
This is a great tool :D
I searched a while and tried different things, and yesterday I found this and I'm very happy with it! :)

I'm just a little worried because mozilla warn's me to install it because of dangerous permissions. When you fit their bureaucratic policies you get 5 stars :)
