In an article on eff.org about Simple Changes to Stop Online Tracking https://www.eff.org/deeplinks/2012/04/4-simple-changes-protect-your-privacy-online They are saying go to Edit -> Preferences -> Privacy. Under "History", choose the drop down "Use custom settings for history". But if I am not wrong in Firefox 29.0 under Edit there isn't any preference rather under Tools we can select options to perform these steps right? I thought as it is about Firefox I should share here. Thank you
