One of the things users of Google's open source Chrome browser like best is its automated way of collecting the sites users visit most in one place, represented as thumbnails. The Opera browser's Speed Dial feature does a similar thing, and it's one of the best-liked aspects of Opera--a time-saver. If you're a committed Firefox user, you can get an extension called Speed Dial that lets you zoom immediately to the sites you visit most. It's very handy to have, although it doesn't have quite the underlying automation that the Chrome version has. For a look at how it works, see the story on WebWorkerDaily, and if you're interested in more good Firefox extensions, see our Firefox Superguide.
