    You can increase the height properties in the iframe embed code, please give it a try.

    <iframe allowtransparency="true" src="//www.jotform.us/form/20625490612145" frameborder="0" style="width:100%; height:465px; border:none;" scrolling="no">

    Let us know if this works.

    hi Brian,

    in your Firefox option, check the ff:

    1. In Content, Enable Javascript should be checked.
    2. then click on "Advanced..." in Enable Javascript
    3. then, in Advance Javascript setting make sure all 3 are checked 

    i was able to overcome this in my Firefox, using the steps.
    please see screen 

    glad to help.

    @ invisibleland

    No problem, just an added info this is the downside of using iFrame version. Every time you change your form, you must update the form code on your site. Since the height of the form needs to be hard-coded, the form size will change and the iframe height will need to be updated.
