Just came across this discussion, which on first sight looks rather worrying:

The file mentioned in the thread, sessionstore.js, does not exist in any of my numerous profiles. There is a directory called sessionstore-backups which has a number of files totaling about 1M. The folks in that thread need to get a life. :-"

EDIT: sessionstore.js exists in sessionstore-backups directory after FF is shut down. I noted this yesterday but the board has been a little wonky of late.

FF 59.0.1 - FF 60b5 - FF 61a - Palemoon 27.6.2 - TB 52.6 - Mac OSX 10.13.3

I believe in current FF, its a transitory file.
It exists at FF start, then gets move/renamed (or something or the other) to /sessionstore-backups/recovery.js, then on FF exit gets written back out to {Profile_Folder}/sessionstore.js.

(I'm sure that's not totally right, but something along those lines.)

Virtualfox persona

Are you ready for deprecation of XUL & XBL & XPCOM extensions? Not?! Try Firefox ESR

noticed it before: ... st-2620793

its the session restore intervall (default = 15s = 15000) for the "recovery.js" (re-)writing.
