The dropdown menu on firefox- the one that shows when you click on the down arrow to the right of the address bar- shows several sites that make sense would be there, google, yahoo, facebook, etc. But how do they get there? for instance, also on the list is a link to a specific Straight Dope message\* thread\* that I viewed and posted to a few times months ago. Why was that thread chosen, and not others since? Why a specific thread, and not simply [Straightdope.com](http://Straightdope.com)? (most of the other sites listed are just the domain, ie, [espn.com](http://espn.com))

Just curious about firefox’s methodology.

FF3+'s address bar, now called the “AwesomeBar”, combines frequency and recency into “frecency”.

Sounds silly, but read more about it if you’re interested: [Frecency](https://developer.mozilla.org/en/The_Places_frecency_algorithm)
