I am able to use the visualforce page as a button totally fine to convert some information from a custom object into PDF format, but my users get the chrome error "This content is blocked. Contact the site owner to fix the issue. I have tried changing their browser settings to no avail and I have looked for the salesforce session settings described in this post (Cookie error with embedded VisualForce page in Chrome) - Require secure connections (HTTPS), Require secure connections (HTTPS) for all third-party domains. I can't find them. I will include my code below but I believe this is a settings issue. Some text has been changed so as not to identify the company and the code is currently not pretty because I have been messing with it to try and fix this issue.
