The IE version is 7, and Firefox is 3.5.8, I tried to use the following to test the xforms in my computer without success (didn't show the submit button): I tried to remove the html tags and leave only the section between <xforms> and </xforms> and save it as a xml file, still no working. How to enable XForms in IE and Firefox, and besides w3.org (I l already read the articles but got no idea), where to get some help on XForms?
XForms is not supported by any browser natively. There are add-ons that will make it work but you'd have to google for those.
You may see it working on the web site but it's transformed on that site server side. No browser implements it natively, unfortunately, but here are some add-ons that will implement it along with this implementation list.
