therealsujitk those are new warnings added by Firefox regarding the new SameSite feature that has been added to the cookie spec in browsers.
We should take a look at implementing the SameSite cookies in Flarum in a later release.
This is however just a warning about new best practices and doesn't cause any issue with the current Flarum version. Flarum is already protected against cross-site vulnerabilities with the use of CSRF.
Regarding the Google Analytics cookies, there's indeed nothing we can do. Seems like Google will have something to change in their code at some point.
