Featured Firefox Extension: Add drag-scrolling and momentum flicking with Grab and Drag

Windows/Mac/Linux (Firefox/Thunderbird): The Grab and Drag Firefox extension adds grab-and-drag scrolling (like you're used to in PDFs), flick gestures, and momentum scrolling to Firefox (similar to the iPhone's flick-to-scroll). Grab and Drag works with any mouse and can be tweaked to your liking if you're keen on the idea, but it seems particularly worthwhile for anyone working on a tablet PC, since it also works with your pen-based input. If you like the feel of the grab-and-drag scroll—or maybe you're using a 2-button mouse and you want a scrollwheel replacement—this extension will do the trick. Grab and Drag is free, works with Firefox, Thunderbird, and Flock. Thanks Eric!
