Why does Microsoft Edge continue to store Third Party Cookies?

Question

Why does Microsoft Edge continue to save Third Party Cookies and Site Data?

Under 'Privacy, search, and services'. I have set Tracking Prevention to 'Strict'.

Under 'Cookies and site permissions'/'Manage and delete cookies and site data'/'Block third-party cookies', I have set to ON.

Under 'Cookies and site permissions'/'Manage and delete cookies and site data'/'See all cookies and site data' it shows 'All cookies and site data'

Within this table you can filter 3 ways: all, first party, or third party.

As I have blocked all third party cookies etc, there should not be anything under the third party filter.

Here's what's stored:

Cookies and data stored for sites you have browsed Filter by: Third party

---

live.com 990 bytes • 30 cookies

---

microsoft.com 104 MB • 21 cookies

---

microsoftonline.com 0 bytes • 19 cookies

---

google.com 2 KB • 9 cookies

---

youtube.com

300 KB • 7 cookies

I think there were some other sites, which I have already deleted.

So, I am asking, can Microsoft/Microsoft Edge fix this?

Answer 1

Hi

Thanks for your reply.

If this kind of function has a problem, I recommend you to use the built-in feedback function of Edge by pressing Alt+Shift+I to report this issue to the developers and wait for them to fix it.

Answer 2

The Allow and Block settings also don't work properly.

If I use Allow, it says that it will also allow third party cookies for the specified site, when my intention is Block All third party cookies, as indicated by the Block All third party cookies setting above the Allow a Specific Site setting.

If I use Block the specific site Bing.com, it still allows Bing.com site as a first-party, after missing it as a third-party.

Maybe there are other sites like Bing.com

So, yes, Microsoft Edge thoroughly confuses first and third party cookies.

Thanks

Hi

Welcome to the Microsoft community.

We have tested your issue and we were able to reproduce it. It seems that there might be some problems with the Cookies-related features in Edge recently (for example, some users found that Cookies are automatically cleaned up, and some users said that this kind of problem can be solved by adding to the Allow list, so you might also be able to prevent Cookies from being written by adding to the Block list). Please report this issue through Alt+Shift+I . You could also try to see if downgrading or using the Canary version is effective. If it is, you can temporarily use these versions of Edge.

If all can't works please wait for them to fix the related problems
