GoToURL not working in Firefox

I have made a page using frames and used Dreamweaver's GoToURL behaviour to
open three pages in three different frames simultaneously. It works when viewed
in IE but does not work at all when viewed in Firefox.
The page can be seen at www.victoriablomster.dk. View it in IE to see how it
should work: When clicking on the image icons to the left and right, the images
appear in bigger size in the middle of the screen. When clicking on one of the
three navigation links on the top of the page, a new set og images and/or text
appears in the frames underneath.
The question is how I make the navigation work in Firefox? Perhaps there is a
script or piece of code that makes it work?
I need to clean up the code and am working on that. However, since it has not
fixed the bug, I just refer to the homepage above, where at least everything is
working in IE.
It has started to drive me nuts - please help.

Why do you need all those frames on that page? I really see no reason for it
when looking at the code for your page. All you have there are pictures. And
if you only have one row and really need to use frames you should be using
iframes and not framesets.

If there is an idea you are looking to remake for your site give us an idea
and more than likely we can give you an easier way of making these pages
without frames.

Hi SnakEyez

Actually, I would rather not use all those frames. You say I can do it with iframes instead? No browser problem I suppose... I'll take a look at it, thanks.
