DownThemAll (or just dTa) is a powerful yet easy-to-use Mozilla Firefox extension that adds new advanced download capabilities to your browser. DownThemAll lets you download all the links or images contained in a webpage and much more: you can refine your downloads by fully customizable criteria to get only what you really want.
DownThemAll is all you can desire from a download manager: it features an advanced accelerator that increases speed up to 4x, it allows you to pause and resume downloads at any time and, last but not least, it’s fully integrated into your favorite browser. Latest stable version is 2.0. It includes a lot of new features, refinements and bug fixes, most notably support for Firefox 4, speed limits, mirror management and better platform/OS integration.
DownThemAll is open-source and freeware. No Adware, no Spyware, no hidden costs!
