Firefox complains about cookie same site attribute

[fosterfarrell9]

Apparently, there is a problem with our cookies and their same site attribute. In the future, these cookies will be declined.

I alreay tried this and this gem to fix the issue, but none of them worked.

Adding an initializer config/initializers/session_store.rbwith the following content:

Rails.application.config.session_store :cookie_store, key: '_mampf_session', same_site: :strict

Fixes the issue for the (most important) session cookie. For the other cookies I would suggest adding a "helper" in application_controller.rb:

  def strict_cookie(val)
    {
        value: val,
        same_site: "Strict"
    }
  end

and calling it like this:

cookies[:locale] = strict_cookie(I18n.locale)

instead of

cookies[:locale] = I18n.locale
