        @mathias @ledahulevogyre @angealbertini That's in fact what Firefox does, but that only stops one of the attacks, so not a complete fix

        AFAICT `SameSite=strict` or even `SameSite=lax` would prevent this, yeah. As for your other question, I refer to @tomvangoethem ;)

        @gondo I don’t think it’s publicly available, but let’s ask @tomvangoethem himself.
