Firefox: Any way to specify white or black lists for the history tracker?

I use Firefox very intensively, and from time to time I clear the browser history. But unfortunately the history is being filled very fast and it always keeps the history I'm not interested in:

• Some sites does not make any interest for me at all, and I would like never include them to the history tracker.
• Other web applications, like Google Reader, use #-links to navigate through the application content, and e.g. for Google Reader the old URLs simply become obsolete because I use "Mark as read". So I don't even see any reason of tracking the #-links in history.

Is there any way/extension/etc to support the features to support either white-lists or black-lists, or particular URL tracking for Firefox? Thanks in advance.
