If you enable this policy setting, a user cannot set the number of days that Firefox keeps track of the pages viewed in the History List. The number of days that Firefox keeps track of the pages viewed in the History List must be specified. If you disable or do not configure this policy setting, a user can set the number of days that Firefox tracks views of pages in the History List.

Check content

Type "about:config" in the address bar of the browser. Verify that the preference "places.history.enabled" is set to “true”, and locked. If the parameter for the history preference is set incorrectly, this is a finding. If the setting is not locked, this is a finding.

Fix text

Ensure the preference "places.history.enabled" is set and locked to the value of “true”.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
