Mozilla Browsing History and Bookmarks - Should Be Separated

I think that the ‘Browsing History and Bookmarks’ clean option under the Mozilla Firefox category should be separated to two individual categories ‘Browsing History’ and ‘Bookmarks’.

Some people want to keep their bookmarks but want to remove there history - at the moment CSC can’t do that.

What does everyone else think? Anyway who deletes there bookmarks - Should this clean option even be there?
