Pub 2003 produces two versions of code. One for IE, and another for other
browsers. For some reason when you fill a text box with a color in Pub 2003,
it converts that text box to an image for FF, and kills the links. If you
remove the fill color, the hyperlinks will work in FF. This of course messes
up your design.

I have found one workaround. Remove the fill color in your text boxes with
links. Then create a new text box without text, but with the fill color
exactly the same size as your text box with the text and hyperlink. Drag the
color filled text box over the one with the hyperlink, use the "snap to"
function to make sure that the edges of two text boxes line up exactly, then
go to Arrange > Order and Send to Back. The hyperlinks then survive Publish
to the web.
