Bug 258002 – "Advanced privacy protection" should not be blocked on first-party sites.

• Status: NEW
• Component: New Bugs

"Advanced Privacy Protection" also blocks communication when a request is made by first-party site.
You should not be blocked if a request is made by a first-party site.

[John Wilander]

Hi! Could you explain what is blocked, please? Is it a subresource request? If so, does the subresource request start out as first party but CNAME-mapped to a third party? Thanks!

Hi! Thanks for your comment.
Here are some examples I found.

Thanks for the information!

I think that in the case of https://www.instagram.com/logging/falco, we should definitely not be blocking that, since it's a proper first party — do you happen to have an example instagram page where you're seeing that? (I tried going to a couple instagram pages in private browsing in Safari 17 on Sonoma, but didn't observe that connection being blocked).

With regards to the others:

• go.adjust.com is a CNAME alias for pi-ue1-public-lb-f0209c6950285322.elb.us-east-1.amazonaws.com

• b92.yahoo.co.jp is a CNAME alias for edge.g.yimg.jp (this one is perhaps a bit unfortunate since yahoo.co.jp and yimg.jp are first parties in practice, but we don't have an explicit exception for that).

• adservice.google.co.jp is a CNAME alias for pagead46.l.doubleclick.net

• aax-fe.amazon.co.jp is a CNAME alias for aax-fe.amazon-adsystem.com
