Hi there,

I've been trying without much luck to find out when or in what Firefox version, the config setting network.cookie.sameSite.schemeful will be set to 'true' by default?

Can anyone point me in the direction of where this information is or let me know the answer if they already know it?

And I'll apologise in advance if this is in an obvious spot that I've just stupidly missed.

Thanks! Simon

I don't think that it's known when this feature will be enabled in release (TBD), so this likely will not happen shortly.
