:confirm in Mozilla Firefox

I use the following code to link a picture so that it refers to a
blank link and relays a message after it is clicked:

<%= link_to_image "images/photos.jpg", "javascript:;", :confirm =>
"There are no pictures." %>

In Safari everything works perfectly for me, but when I use Firefox,
there is a blue border around the clickable picture, I think to
indicate it is a link. I have tried using CSS to get rid of this, but
it doesn't seem to work. Is there anyway to get rid of this blue

:border => 0 in the html options.
