problem with forms viewed in Mozzila Firefox browser

I am having a problem with a form that when directed to the page viewed in Mozilla Firefox web browser the form shows briefly then disappears, when refreshed it still does the same, the only way to get over this is to restore page down then restore to full size, I have checked with other browsers and don't have the problem I am wondering if its a bug in the Firefox browser any help please

Hi,

I checked your site and I was able to duplicate the issue you are reporting. As per checking, you have embedded the form using the script method. Can you try to embed your form using the iFrame embed method? To get the iFrame embed code of your form, you can follow the instruction provided in this article: Getting the Form iFrame Code.

Do let us know if you need further assistance.

Regards.
