Author Suspend a single process to a swap file to reload later?

I want to be able to suspend a single process (e.g FireFox) and then
shut down my Linux Fedora Core 5 box, and then start up again and then
restore the FireFox process to exactly the place it was before it was
suspended. So all windows and tabs will have exactly the content they
had when I suspended that process.

I want to do this on a desktop PC. I do not need a full box hibernate.
Though that'd be handy.

I use KDE 3.5.5. I used to have Gnome as the desktop and I think it had
a full hibernate. But the shutdown choices for KDE do not have such a
feature.

I've gone into KDE Control Center | KDE Components | Session Manager |
On Login and selected "Restore manually saved session". That gives a
Save Session option. But if I use that, shut down, reboot, it just
freshly starts the list of apps I previously had running. Though it
remembers some things about which command interpreters were open.
Still, it is not saving the entire state of a process.

So is there a way to save the entire state of a process?

Is there a way to save the entire state of all user processes for my
login session?

I'm looking for either selective single process hibernate or a wider
ranging hibernate and restore.
