That's really a great extension.

It "only" deletes the history, but not cookies, cache, website data or anything else and is unfortunately not suitable for me, although I like the clear menu structure and the good documentation.

add a feature to whitelist or blacklist specific sites

Thanks! The addon works well to clear my BROWSING history, but it does not clear the search bar history (which I use with various search engines such as google, amazon, wikipedia etc. ). To do so I have to (remember and) manually clear 'Form & Search History' from the preferences, which is annoying.

This is very easy to use History Cleaner for Firefox.
