FlashGot is a free Mozilla/Firefox/Thunderbird extension (compatible with Netscape too), meant to handle single and massive ("all" and "selection") downloads. This software bridges the gap between IE download managers and Firefox. Please note: You will need a download manager in addition to FlashGot, such as FlashGet, Fresh Download, GetRight, Net Transport, NetAnts, or ReGet.
