Why does this CSS image-replacement work in FF, not Safari

I'm trying to make a portfolio website using just CSS. This technique works in Firefox, but in Safari I have to hold the mouse button down to make the main image stay on-screen. Is this a Safari bug?

Bug? Feature? either way it doesn't work.

...to realize that maybe web development is not for me.

It's possible that Safari (and Opera) are actually fine and FireFox is broken which allows the technique to take advantage of FF's bug/quirk to make this hack work. I don't know.
That's neither the best nor only way to achieve that effect.
