1. What should be "privacy" settings for a more secure firefox 3.6.18, in ubuntu 10.04 LTS. Should one choose "never remember history" or "use custom setting for history". In case I choose the later, what should be cookies settings: accept cookies (y/n), accept third party cookies (y/n), keep until (I close firefox) (y/n), automatically start firefox in a private browsing session (y/n). 2. This is related to above issues. In case I try the option "never remember history", I will have to enter web address every time I start firefox and I will have to give my login name for various sites each time. This is annoying. So should I rather try custom setting for history? I am ready to have this annoying feature in order to make the browser more secure. I am not sure what harm cookies can do in ubuntu.
