I was wrong about the actual security policy, but multi-process is still a big security win.

And not so related to this, but from what I've heard about cracking competitions a few while ago, Firefox was not even included, it was considered too easy. Maybe my sources were just bad.

And I say this as a Firefox user for the last decade or more.

That may have been true at some point, but I don't think it's true now. E.g. Project Zero finds Firefox sandbox escapes noteworthy.

That was before Firefox desktop had any multiprocess support at all.
