Sync all sessions across computers

[rebop]

I would like to keep all computers curent with my sessions. I f=do this with many other things simply by syncing selected files. Where are the sessions kept in the Firefox Profile so I can try syncing this way? I have searched everywhere I can think of. And exporting/importing is much too much work for all I have.

Thanks.
