This Help Article: ( [[https://mzl.la/3bGN6WJ |"Manage local site storage settings"]]) says: '''Allow or block websites from storing information''' "You can set up Firefox to always allow or block specific sites from storing information. '''You can also allow a site to store only for a single session. ''' " So I added a URL into 'Cookies and Site Data' > 'Manage Exceptions' with the option "Allow for Session". But it appears to have no effect. The site's cookies and data don't disappear from the "Manage Cookies and Site Data" window after Firefox is quit. Does "Allow for Session" mean that a site's cookies and data will be deleted when Firefox is quit? If yes, the feature is not working ... in my version of Firefox which is 115.32.0esr. Or, am I missing something? I have "Enhanced Tracking Protection" set at "Strict", if that has any relevance. Thanks !
