Only on Firefox “Loading failed for the [removed] with source”

Question

I want to integrate Marketo form with my existing website on yii framework. My code works on all the browsers except Firefox.

Excerpt from my code:

Answer 1

I ran in the same situation and the script was correctly loading in safe mode. However, disabling all the Add-ons and other Firefox security features didn't help. One thing I tried, and this was the solution in my case, was to temporary disable the cache from the developer window for this particular request. After I saw this was the cause, I wiped out the cache for that site and everything started word normally.
