Firefox Private Browser Hiding ALL Marketo Embed Forms

Anyone else get this problem?

When I use Firefox Private Browsing to visit my website, all of my Marketo embedded forms disappear. It only happens through the new Firefox Private Browsing feature.

    Sure, new FF has built-in Tracking Protection. This significantly affects both forms and Munchkin.

    You can (a) disable TP or (b) try loading all your forms from a CNAME at your domain as opposed to from *.marketo.com.  Search "CNAME" for a bunch of discussions on this.

    The issue is not with me seeing the forms; my worries are with my potential customers that won't be able to see the forms.

    Thanks for advising with that alternate solution, however, I don't believe that changing the 15+ forms that I have on my website is the solution. Marketo should do something about this. When I visit websites that use Hubspot embed forms with Tracking Protection enabled, they show up fine, and they are loading the forms from another domain as well, so the issue is with Marketo only.

    Huh?  It's the public tracking protection list that specifically has Marketo domains on it; what would you expect Marketo to possibly do about it?  The fact that TP blocks detected Munchkin hits, for example, is totally sensible.  Marketo is running a tracking service.  You can try to obfuscate this by using your CNAME.  Ultimately, however, if someone is trying not to be tracked, you shouldn't subvert their wishes: that's like trying to sneak JavaScript in even if someone is running NoScript. 

    I don't know what you mean by "changing" your forms, in any case.  I'm talking about loading them from your CNAME. You don't have to change anything on the form itself, just the way you load them.

    I just noticed this today as well while tracking down an issue on a particular form & program!  Good catch Sam Siskind​

    Thanks for replying Geoffrey. Hopefully we can get a fix right away because this is simply unacceptable. I have created a case with Marketo tech support, it would help if other people can do the same to raise priority.

    I'm not sure what Marketo can do from their end, as it is more of a browser issue.

    Most people are unlikely to use private browsing, incognito and whatever the IE equivalent (if any) there is.

    Luckily my team already has a domain alias set up and we can go through our content pages and the way we pull in the forms to update.

    I think that is the cleanest way, option (b) above, to remedy this situation.

      We noticed this issue too. Both our Marketo Forms and RTP Campaigns don't work in Firefox In-Private Browsing. But everything works for IE In-Private Browsing and Chrome Incognito. Definitely looks funny when my in-page default ads don't show on our website? @David Myers or Yanir Calisar any ideas on this? 

      Thanks for the tip Sanford:

      Glad to see I wasn't the first to have this problem. Unfortunately, it gets more complex when you use multiple domains. Anyone using iframes to for solve this? Links for the discussions and landing page examples where people have successfully solved the issue? Much appreciated friends!

      An iframe will not help you at all here. Iframes don't fool the browser about where content is coming from, though they may fool users.

      So for clarity, using cname in iframe will not help? This solution was suggested to me by Marketo support. I wanted to know if it worked for anyone.

      Shout out to Cedrick with Marketo Support who provided a solution that worked, with very basic, detailed instructions to implement, and to @Sanford Whiteman who challenged the first answers I was given:

      The issue includes Munchkin.js, Forms.js, and any other remote src=’….’ Resource and is not exclusive to Marketo. If the location in any src=’someURL.com’ does not match the domain you are on, that is getting blocked.

      The Workaround (that worked for me): Please try this workaround by embedding forms and replacing this bit:

      <script src="//app-sjst.marketo.com/js/forms2/js/forms2.min.js"></script>

      With: <script src="//{{landing page CNAME}}/js/forms2/js/forms2.min.js"></script>

      If the above does not work:

      Please try to create a new CNAME that points to ‘munchkin.marketo.net’ so they can embed munchkin on external pages as: <script type="text/javascript" src='//{{munchkin CNAME}}/munchkin.js'> </script> <script>Munchkin.init('you munchkin code');</script>

      However, this does not help for internal pages using drag and drop and the system appended Munchkin. Or for any internally hosted images, files, or CCS.

      Note 1: I wasn't quite sure at first but I entered it without the http: just "//go.domain.com"

      Note 2: There are 2 places in the embed code you have to remember to switch out the app.marketo... with your CNAME.

      Additional notes (tested and validated) important in my use case, relevant to my side questions:

      1. It will work cross-domain if you have multiple domains. I.e. CNAME a will work on domain b. (but do you REALLY want to do that in the long-term? Will future updates catch this? Probably safer to use the matching CNAME, which leads to:
      2. There doesn't appear to be a (published or openly known) limit on CNAMES, as long as they point to the same DNS. @Sanford Whiteman - thank you for causing me to question this further! You saved me a ton of work and time!

      Glad to help, but --

      The issue includes Munchkin.js, Forms.js, and any other remote src=’….’ Resource and is not exclusive to Marketo. If the location in any src=’someURL.com’ does not match the domain you are on, that is getting blocked.

      -- this is not correct.  Same-domain policy doesn't stop you from loading remote scripts.  If it did, billion-dollar CDNs would be out of business.

      Rather, this is specific to known tracking domains.  Any information you got to the contrary is wrong.

      It's easy to get confused, but I want to make sure there isn't any more misinfo on this as it makes the solution harder to locate.

      Note 1: I wasn't quite sure at first but I entered it without the http: just "//go.domain.com"

      That's a protocol-relative URL.  It's not so much "without the http" as "adaptive to http or https"  It will inherit the protocol of the calling document.  Thus on example.com it will load the script from go.domain.com, while on example.com it will load from go.domain.com.

      This format is critical because URLs must load resources to avoid warnings and, in modern browsers, additional failures.

      1. It will work cross-domain if you have multiple domains. I.e. CNAME a will work on domain b. (but do you REALLY want to do that in the long-term? Will future updates catch this? Probably safer to use the matching CNAME, which leads to:
      2. There doesn't appear to be a (published or openly known) limit on CNAMES, as long as they point to the same DNS. Sanford Whiteman - thank you for causing me to question this further! You saved me a ton of work and time!
      1. There's no reason to not use a single CNAME for this, unless it's to separate parts of a company that aren't expected to appear in each other's HTML source.  Tracking protection doesn't care what CNAME you're loading from as long as it doesn't see it as suspicious.  What you could worry about more is when tracking protection starts checking to see what your CNAME points to: it's not like you're really hiding marketo.com.  The only reason they don't check this now is that it could take a lot of resources on your computer (imagine a chain of CNAME --> CNAME --> CNAME --> marketo.com).
      2. In Marketo, there may be a limit.  In DNS in general you need not be concerned.

      Thank you so much @Sanford Whiteman for clarifying again. This was cut and pasted from my support case. None of us like misinformation.

      The reason for multiple domains is simple and not usual for many brands - microsites for various campaigns. But, the multiple CNAMES solution is intended to solve for (and only necessary if) the CNAME matching the page URL (vs avoiding a KNOWN TRACKING DOMAIN) is the root of the blocking issue.

      We again have a conflict with what I was told by support. Given that I'm able to do cross-domain CNAME embedding and it works, I think you're correct.

      Thanks again, and I really hope this helps someone else (and saves them a bunch of time).

      Hi all,

      For more info on this issue: Tracking Protection in Private Browsing | Firefox Help

      Would require Marketo to work with Disconnect to get removed from the list...

      It also happens when you have 'Never remember history' in the History settings, which technically acts as the private browsing mode. CNAME alias won't work if your site is loaded over HTTPS, because of the SSL certificate mismatch. The only solution we've found is to proxy all the communications with your marketo subdomain through your domain. We use mod_rewrite + mod_proxy for this purpose, here is the example .htaccess for apache 2.2:

      <IfModule mod_rewrite.c>
      RewriteEngine On
      RewriteRule ^js/forms2/(.*) http://app-sjint.marketo.com/js/forms2/$1 [P,L]
      RewriteRule ^form/getForm http://app-sjint.marketo.com/form/getForm [P,L]
      RewriteRule ^form/getKnownLead http://app-sjint.marketo.com/form/getKnownLead [P,L]
      RewriteRule ^index.php/leadCapture/save2 http://app-sjint.marketo.com/index.php/leadCapture/save2 [P,L]
      </IfModule>

      then, to include the forms2.js from your domain:

      <script src="//company.com/js/forms2/js/forms2.min.js"></script>
      <form id="mktoForm_1234"></form>
      <script>MktoForms2.loadForm("//company.com", "XXX-XXX-XXX", 1234);</script>
      But with this approach user cookies are not proxied, so ideally you should use this method as a fallback only, the full example is at Solution to Embedded Marketo Forms Not Showing Up in Firefox - Quora

      Your Marketo LPs should be running over SSL anyway (there's no barrier except cost). 
      You can either provide your cert to Marketo, buy their bundle, or (an nearly zero-cost route) use CloudFront and an auto-gen'd ACM cert.
