I updated to Firefox 3.6 and I have nav bar on several sites that I created in Fireworks by exporting the html. On these pages some image links work and some do not. The mouse does not show a cursor change even. This did not happen before the upgrade and all works fine in IE and Safari. Here is the website.... http://www.nightkitchenbakery.com. As you will see "menu" and "breakfast treats" buttons works fine but not" specialty cakes" button and many others.
Actually I created a temporary fix. It seems like different height slices throw something off, I make all of the slices that are links the same height and put them on the same line it works, although the rollovers are not showing now. Very very strange
I know this isn't helpful, but you shouldn't use Fireworks exported HTML for live sites, anyway. The code isn't robust enough. Fireworks HTML is meant for prototypes. You should build your site in a page/site authoring tool (such as Dreamweaver) or by hand in a text editor.
No, it's a good answer. I need to get away from relying on it as this incident proves. Thanks for you help.
