When I close FF via CMD:
Process process = Runtime.getRuntime().exec("taskkill /F /T /PID " + PID);And reopen FF I get the following:
Sorry, we're having trouble getting your pages back... We are havingtrouble restoring your last session. Select Restore Session to tryagain...
I see the option to Restore Session or Start New Session.
Firefox: Sorry, we're having trouble getting your pages back..
My question is: Does this imply that FF was unable to preserve cookies or any other persistent data from the previous session or it solely means that FF will restore pages from the previous session? As far as I can tell cookies are preserved because when I go to options -> privacy and security -> manage data I see cookies from the previous session. To phrase my question a bit differently, if I chose NOT to restore the previous session is there any way for a website (that I visited in the previous session) to tell that I did not restore the previous session (i.e, based on cookie data or some other persistent data)?
