How to resove: Firefox prevented this page from loading...
Blocked by Content Security Policy
An error occurred during a connection to www.scribd.com.
"Firefox prevented this page from loading in this way because the page has a content security policy that disallows it." On IE, the message said it cannot be loaded in a FRAME. It's a letter!
I looked at and tried some instructions in Content Blocking. No solutions are there. Thank you.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0
This isn't about content blocking, but about CSP policy rules. The website tries to load a page in an iframe and that isn't allowed.
The only workaround is to open the frame URL in a new tab (right-click: This Frame -> Open Frame in New Tab).
The option to right click to open isn't in Firefox, just IE. If so, it wouldn't bother me.
Hi CiaoBella1, could you share a link to a page where you have this problem?
Hi CiaoBella1, the framed page loads from:
and the page is sent with this header:
content-security-policy: frame-ancestors 'self'
"frame-ancestors" refers to what sites/pages are allowed to embed the content, and 'self' limits the embedding to https://www.scribd.com
That seems like a mistake, but it needs to be fixed by scribd. Until then, you can pop the frame that didn't load into a separate tab using:
right-click > This Frame > Open Frame in New Tab
I only understand that scribd has the issue.
Pop the frame? Don't understand, but I know that you cannot right click from FF.
I read the letter already. Can I assume it's a one-off issue (or low probability)?
Thank you for your effort and response. You shaved, didn't you?
Hi CiaoBella1, yes, I shaved it.
I'm puzzled about this part:
I know that you cannot right click from FF.
You cannot right-click the "Blocked by Content Security Policy" text and get the context menu? Does it work any better if you hold down the Shift key while right-clicking?
No website was underlined and I could not see that the website was scribd (if I remember correctly). So yes, I could not get any reaction to a potential right-click action. I think I learned from IE that it was scribd.com.
Just went to the website from the link I posted above. Apparently scribd.com fixed their error/s because the letter is now visible on the HR.
Interesting - yes, I am sure the first screen box was what I saw (I've never worked w/it before) and ignored. The developer tools I don't know how to work with at all.
Ahh. Thank you.
