I've just noticed that one of my questions has been merged with another question. I've no problem with this.
However the text of the other question doesn't seem to match the question title and therefore it doesn't match my question either.
i've already got the answer I wanted so no problem but I think its a bit confusing if others see it.
My question Install XULRunner 2.0
the other is here How do I install XULRunner since it's a requeriment for Pencil?
