I'm not sure if this is the best place to post this issue, but any help is much appreciated.
We have a form on our Magento site, that when submitted on Firefox, prompts the following security warning:
Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection and could easily be read by a third party.
Are you sure you want to continue sending this information?
I have contacted our hosting and they explained it's an issue with the code, "you would typically getting a notice like that if you're calling assets over an http on a page that is using https."
If anyone has any insights as to how to avoid this from a development perspective, please let me know. Thank you in advance for the help!
