Rated 5 out of 5 stars

Very nice. With the default settings it seems designed mostly to get rid of old history and dead links, but if you change the time limit to 0, and you have it execute the deletion whenever Firefox is closed, then it actually functions as a constant filter of parts of your History based on specific keywords. It all makes so much sense to me that I think it should be a default feature of Firefox some day.

This review is for a previous version of the add-on (0.12).
