このプラグインはFirefox 3.1用です。

== Command ==
:clearp[rivacy]:
    既定の設定でプライバシーデータを削除します。

:clearp[rivacy] -l[ist] {itemName}:
    {itemName}のデータを削除します。
    省略すると既定の値が用いられます。
    既定の値は「プライバシー情報の消去」設定で行えます。

    {itemName}:
        cache: Webキャッシュ
        cookies: Cookie
        offlineApps: Webサイトのオフライン作業用データ
        history: 表示したページの履歴
        formdata: フォームと検索エントリーの履歴
        sessions: 現在のログイン情報

:clearp[rivacy] -t[ime] {timeSpan}:
    現在から{timeSpan}分の期間のデータを削除します。
    省略すると既定の値が用いられます。
    既定の値は、about:config にある privacy.sanitize.timeSpan になり、
    0:全て,1:1時間以内,2:2時間以内,3:4時間以内,4:今日 となっています。

    期間内指定で有効なのは
        + cookies
        + history
    のみで、それ以外は指定にかかわらず全て削除されます。

    {timeSpan} format:
        数値m数値d数値h
            - m は30日
            - d は日数
            - h は時間
        で 1m2d3h は 32日と3時間 という意味になり、現在から32日と3時間前までのデータを削除します。
