You can control the page via the DOM and fill the fields from FoxPro code directly. You basically get a reference to the document then do document.getElementById() to get each field on the form and set its value property.
Pretty easy to do actually...
Here's an article that describes some of this:

Note this will only work with IE. If you have to use another browser then you have to automate via keyboard events (which doesn't work very well with browsers - not recommended especially since the HTML layout can easily change).
