    Form doesnt seem to be working on updated Firefox Browser

    Asked by mitchy2009 on August 20, 2013 at 06:34 AM

    Hi Guys,

    A form that i have created on your site doesnt seem to be working on the latest version of firefox after embedding the form in to our company website.

    Is it optimised for the latest version of firefox?

    Sorry for the inconvenience that may have caused. Can you please try to re-embed your form code into your website using iFrame method if that fixed the issue or not?


    Thank you!

    Hi Jotform,

    Its strange because it works fine in IE10 using the normal embed method, but doesnt in firefox and chrome.

    Ive also tried the IFrame embed method too and im getting the exact same results.

    Ive asked my web hosting firm just to check everything on there end so ill let you know.

    What is the Firefox version and the OS you used ? I am using one the latest version for Ubuntu Canonical (21.0) and I am able to work perfectly

    Also, make sure that javascript is enabled on that version. Otherwise please use the iFrame version of the form, make sure you just grab what it is between the iFrame tags, and that you remove the script type part of it, as in the example below

    <iframe id="JotFormIFrame" onload="window.parent.scrollTo(0,0)" allowtransparency="true" src="//form.jotform.co/form/31528355552859" frameborder="0" style="width:100%; height:457px; border:none;" scrolling="no"></iframe>
    <script type="text/javascript">window.handleIFrameMessage = function(e) {var args = e.data.split(":");var iframe = document.getElementById("JotFormIFrame");if (!iframe)return;switch (args[0]) {case "scrollIntoView":iframe.scrollIntoView();break;case "setHeight":iframe.style.height = args[1] + "px";break;}};if (window.addEventListener) {window.addEventListener("message", handleIFrameMessage, false);} else if (window.attachEvent) {window.attachEvent("onmessage", handleIFrameMessage);}</script>

    Hi Jeanette,

    Im using Firefox version 23.0.1. which is the latest.

    It works on IE10 and Safari, but not on Firefox or Chrome.

    That is because you have your website protected with SSL, but your form is embedded normally. Your page doesn't accept any non-secure content. To fix that, you have to re-embed your form securely by following this guide: Setting Up a Secure or SSL Form

    Here's the error, you're not able to see the form: 

    When accepting the unsecure content, the form show up:
