Hi,

I use an extension (FEBE) to backup my browser, as part of this FEBE takes a copy of sessionstore.js. Since I upgraded to Win 10 and Firefox 41 FEBE is generating an error when running a backup. (sessionsstore.js not found)

If I look in C:\Users\michaeltrucker\AppData\Roaming\Mozilla\Firefox\Profiles\y3vhq0bc.default-1446331514952 the sessionsstore.js isn't there. If I close Firefox then the file is created. As soon as I open FF this file disappears?? wft!

If I want to take a copy of the file that holds the info for my session where is it stored while FF is open?

Thanks

Michael

Check out the sessionstore-backups folder. While Firefox is running, you can expect to see:

  • recovery.js: the windows and tabs in your currently live Firefox session
  • recovery.bak: a backup copy of recovery.js
  • previous.js: the windows and tabs in your last Firefox session
  • upgrade.js-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

When you shut down Firefox normally (i.e., it doesn't crash), recovery.js is removed from this folder and used to create sessionstore.js in the main level of the profile folder. When you start up Firefox, the process is reversed. (I don't know why they decided to do it this way.)

Firefox uses the sessionstore.js file in the profile folder to store session data, but this file is only present when Firefox is closed. The sessionstore.js file is created from recovery.js when you close Firefox and is removed and copied to previous.js when you start Firefox to make is possible to restore the session at any time.
