Chrome: If you want to quickly glance at a link within a news article without actually clicking on it, SwiftPreview is a simple way to do it. When you hover over a link, it shows you a preview of the linked page.
Once you install SwiftPreview, you're offered a range of customisation options that let you change the preview size and scaling, and specify any domains you want to block from being previewed. You can also change its behaviour so it only shows previews when you hold the shift key.
SwiftPreview will probably be most useful to avid news hounds who might want to get the rundown of a linked page without actually opening it.
