History and cookie settings
Under the Privacy tab, there are configurable settings for security. The first part of the tab deals with history and saved user information. Granted that remembering multiple usernames and passwords for different websites and Internet services is cumbersome, however it is better than leaving this information where it can be accessed by unauthorized individuals. It is therefore best to uncheck the options for saving history and the auto-fill feature for forms.
The second part of the tab has the cookie handling functionality. Previous versions of Firefox had a blanket approval for cookies, not taking into consideration whether they were cookies from a site, or from the third-party elements on a site.
The ‘Keep until’ option allows the user to specify that they require a prompt before a website saves a cookie on their system. The Exceptions window contains a list of all the exempt websites. It is also possible to set this option to ‘I close Firefox’ thereby emptying the cookie cache every time the browser is restarted, disabling persistent cookies altogether.
There is also the Show Cookies option, where the user can view all the cookies that are currently stored on the machine. The user can review each set of cookies, with all the metadata in the bottom pane. Additionally, the user can delete whichever cookies they feel are not necessary or violate their privacy.
The last pane has to do with the user’s private data, broadly encompassing items like browsing history, search terms and details from forms. It is best to clear this data on a regular basis, or enable the option to clear the data every time the web browser is closed.
