Firefox Input Background Image
Has anyone noticed this?

When you put a background-image into an input field in Firefox Mac/Win, the input borders get distorted (it’s darker…)
I don’t have a fix for it, actually, I am not even sure it’s broken. Also, the blue highlight the input field gets when it is in focus, does not appear when you add background-image to an input field.
I think that’s a very strange default behavior.
It does seem like a strange behavior. I’m sure it would be receptive to the border property if it was specified. However, I would miss the focus, I think that is important for UI.
I have the same problem. it’s really weird.
