Mozilla has delivered the latest of its ongoing, sixth-weekly updates to Firefox, pushing the browser up to version 18.0. As you may expect, the company has packed in a whole bunch of new features, and while most concern the overall running and general performance of the app (read: under the hood housekeeping), there are one or two which many will notice from the get-go. Details, and info on where you can grab the new Firefox, are available after the break!
