uBlock blocking all Marketo Forms from Mac computers

Anonymous

Is anyone else having this issue? The ad blocker UBlock has recently been blocking our Marketo forms (whether embedded or not). I reached out to Marketo support and they said they do not deal with 3rd party issues but this seems like a huge problem for all Marketo customers. Anyone else experiencing this problem? Or feel like testing it on their end?

We have found that PC users do not have the form blocked, just MAC users.

If you are having the same issue I encourage you to open a case with Marketo Support.

Hi Sanford,

Several of our landing pages have custom CNAMEs. I have visited a few other company sites that use Marketo forms and their forms are blocked as well. Any other suggestions?

Thanks!

Post the URL of the form and I'll take a look. The CNAME trick can be easily foiled by an in-depth check, of course. You can route around just about anything like this (say, by going through a non-Marketo IP) but at a certain point there are diminishing returns.

On your form embed code, you can swap out the '//app-****.marketo.com' in the loadForm call with '//<your landing page domain>' which should remediate this issue.

Hi Kenny,

Our web developer tried this and the form is still blocked by UBlock. Any other suggestions?

Thanks!
