Firefox issue with cookie __clsk

[silviagreen]

Using Firefox latest version, I get the following warning:

<<Cookie “__clsk” does not have a proper “SameSite” attribute value. Soon, cookies without the “SameSite” attribute or with an invalid value will be treated as “Lax”. This means that the cookie will no longer be sent in third-party contexts. If your application depends on this cookie being available in such contexts, please add the “SameSite=None“ attribute to it. To know more about the “SameSite“ attribute, read developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite>>

Can this be corrected somehow? Can this cause malfunctionings in the future?

Chromium has started giving a similar warning

Any news on this? Even though the issue is only shown in Firefox the attribute is the same in all browsers, so the scope is not just Firefox.
