Firefox 92 and admin console: "Cookie will be soon rejected"

Hello everyone.
Finally I’m studying keycloak for my first serious project and I’m finding really interesting.

Right now I have configured KC (15.0.2) behind an apache httpd reverse proxy so the SSL certificate is installed on apache.
I’ve noticed this: when I inspect the network tab of “Inspect element” in the latest version of Firefox in the keycloak admin panel I see a lot of the following warnings:
Cookie [Cookie Name ]will be soon rejected because it has the “SameSite” attribute set to “None” or an invalid value, without the “secure” attribute
Cookie name changes between KC_RESET and KEYCLOAK_3P_COOKIE for what I saw.

Is a configuration I missed somewhere? Should I be worried?
Thank you!
