How do I stop Firefox from blocking a website.

more options

How do I stop Firefox from blocking an important website? Each time I try to get to a specific website it doesn't allow the site to come up. If I am trying to get a market quote and/or an update and the page won't load. This appears to be a recent change.

Another block problem I have is stated as the following:

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.

Help!

I posted this reply in the other question you created:

In what way is Firefox blocking these websites? Is that a problem with a secure connection or is something else wrong?

Can you attach a screenshot?

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?


In Firefox 56+ the "Warn me when web sites try to redirect or reload the page" setting can no longer be found in Options/Preferences.

You can modify this pref on the about:config page to enable or disable this feature


You may see a "Blocked by Content Security Policy" message when a website wants to embed content from another website in an iframe and the CSP policy prohibits this or these is otherwise a violation of the CSP rules.

Can you share the address? It sounds like there is an outer page that you're loading, and it has an embedded page which has rules which forbid it from being embedded or framed. You may be able to view the embedded page by right-clicking it and expanding the This Frame menu, then opening the frame in a new tab.
