Well,

If you dynamically set form elements IE uses the name field and firefox needs the ID field.

So you have to set both equal in the code

In the URL form element in de vbgooglemap_display_yourlocation there was a difference in the name and id attribute of the tag so firefox was trying to update the wrong element which already existed on the page but hidden.

Because firefox cannot update two form elements with the same name/id he just stops updating anything.
