Firefox Loads Expires not as 365 but as session

[jasperf]

When we set the cookie to expire in 365 days

this.$cookies.set('cookies:analytical', this.conversionTracking, '365d')

Firefox Developer loads it set as session. This whereas Chrome does load the 365 days. Somehow cookies work and are set well and work for Chrome allowing it to load social media content with cookies set, but Firefox not so much..

Do know our custom cookies load from subdomain and Laravel cookies from main domain it seems. And then Lax is perhaps not working on FF and we need none and secure..? But why I see session and not 365 days is very odd as well Any ideas?
