"Delete cookies and site data when firefox is closed" checked but data remains

When I start a fresh session in firefox there is always some Kb of data showing under the "Cookies and site data" section in settings. How can it have site data and/or cookies when it hasnt even visited anything yet? Whats worse is that sometimes it can be around 8Mb. So even if it is something that firefox itself puts in that folder upon starting a new session why does the data size vary that much? And its not random, it will either be a couple of tens of Kb or around 8Mb.

I have "Delete cookies and site data when firefox is closed" checked. Under "Manage exceptions" there are none. History is set to "Never remember".

I actually just checked now. Backed the text above to a file, turned all my addons off, and exited firefox entirely. Made sure there there are no firefox processes running, started it up to blank tab, and first thing I see is that there are 8.8Mb of data under the "Cookies and site data" section. I press the clear data button and exit entirely again. No processes running, start a new one, and theres 72Kb of data there. What is that?

Where are you seeing this? What files?

I dont know what the files are but Im assuming there are since the browser is saying there is data there. Im going into Settings>Privacy and Security>and then under the title "Cookies and Site Data". Am I wrong in assuming there should be no data there when I start a fresh session with the previously described settings?: I have "Delete cookies and site data when firefox is closed" checked. Under "Manage exceptions" there are none. History is set to "Never remember". Not to mention "permanent private browsing mode" on.

. . . . and theres 72Kb of data there.

If this is all, don't worry about it.

And how about the times when its 8-9MB? Redundant question I guess. Cause its just such a small amount of data so it cant possibly be meaningful or be accessed by software installed on the pc without my knowdledge. Right? I mean what is 8-9MB anyway, its like two 1080p jpegs or something? And we all know whoever said a picture speaks more than a thousand words was a complete moron because we all also know that 8-9MB of data is "nothing"... Right?

Lets try this instead: Can you help me setup my firefox settings so that it actually does what it says it does? I can already hear you struggling to understand the question so what I meant was are there settings that can be edited in such a way that the folder for cookies is actually emptied when a session is closed? Oh and lets not forget to thank you for your 100% useless answer previously as well as in advance for the 100% lack of answer to this. Just a couple of more updates now and itll be indistinguishable from chrome, great work everyone! Thank you for all your help!!!
