Based on some information on the internet (e.g. here), Firefox deletes HSTS information after a private browsing session.
My understanding is that this would mean that the "SiteSecurityServiceState.txt" file located in the Firefox profile directory (under \AppData\Roaming\Mozilla\Firefox\Profiles) is cleared.
I am running FF 42.0 and have configured it (under Options > Privacy) to "Always use private browsing mode".
Now however for some reason this file is not getting cleared. In fact it looks like it is getting populated by Firefox with specific entries.
I am saying this because I cleared the file manually a couple of hours ago and since then I have run a few test sessions (browsing the web for some time, with that "Always use private browsing mode" enabled) and closed the browser after each test session. Now when I checked the "SiteSecurityServiceState.txt" file, it looks like it has the same entries as before.
Here's an extract of some of the entries in it:
- Is it correct that the entries in "SiteSecurityServiceState.txt" should be deleted after a private session?
- Is there some system property that would need to be enabled to clear the entries at the end of a session?
