Why did Firefox prevent a page from loading when it was fine a month ago?

When using Verified by Visa to reload my Tim's card, I got the following message:

Blocked by Content Security Policy

This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.


How can this be fixed?

The website probably tries to load a page in an iframe and the website you try to embed has policy rules that prohibit this. The server would would have to make sure to send the proper HTTP response headers.

You can try to right-click this iframe and use "This Frame > Open Frame in New Tab".

Another user posted a similar problem recently: Why do I receive a security block when I try to complete a "verified by Visa" form to reload my Macdonalds Archcard?
