Rurik

There are a few settings that CCleaner doesn't touch in Firefox that irk me a bit. In %USERPROFILE%\Application Data\Mozilla\Firefox\Profiles\*\prefs.js, a few entries could be redacted: browser.download.lastDir general.open_location.last_url However, in doing some searching here, it seems there is hesitation in having CCleaner clean the prefs.js?
