A developer tool (developer tool) that is indispensable for changing the design of the site and grasping the situation. Of course, those who read this article will know (if you don’t know, you can’t reach it …).

This developer tool has recently come out with a lot of caution signs.

A great number of “A cookie associated with a cross-site resource at …” are displayed. It’s a precaution, so you can ignore it, but if possible, you want to hide unnecessary precautions, right?

Here’s why “A cookie associated with a cross-site resource at …” appears and how to hide this note. The caution display is annoying! !! If you like, please set it.

By the way, it seems to be a warning function adopted from a relatively new version of Google Chrome, so it seems that there are many people like me who are surprised when it suddenly appears.

What is the note “A cookie associated with a cross-site resource at …”? ??

The content of caution is like this.

A cookie associated with a cross-site resource at http://xxxx.com/ was set without the `SameSite` attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.

※Part is different　http://xxxx.com/

Since it is written that you can check the detailed information, actually

Feature: Reject insecure SameSite=None cookies

Feature: Cookies default to SameSite=Lax

I don’t know what it is even if I read it! !!

However, if you take a closer look at the line displayed as a caution, domains that support both http (non-SSL) and https (SSL) (this is called cross-site?) Are always displayed as a set of two. There is a problem with the information sent by these destinations! It seems that (it is just a personal interpretation).

Well, since it is a “caution”, it is not an error in particular, and since it is a Google Chrome browser, you do not have to worry about it, but it seems that your site is being given attention. So let’s hide it quickly.

How to avoid the warning “A cookie associated with a cross-site resource at …”

Start Google Chrome, enter “chrome: // flags /” in the address bar,EnterEnter the key.

Then a screen like this will appear.

If you enter “Cookie Deprecation” in the search window, the screen below will appear. Set the option item on the right side to “Disable”.

Then at the bottom of the screen

Message is displayed, so it is on the right side.Relaunch NowIf you click the button to restart (or manually close and restart), it will be applied and this display will disappear.

… I’m a little sad personally that some of these notes are from Google related sites (crying). Is that because the departments are different? ??
