Although Speed Download is fully optimized for all popular Mac OS X Internet browsers, this specific feature set allows even more seamless integration with the Apple Safari browser.

Via the Safari contextual menu, you can easily disable/bypass Speed Download if you encounter downloading issues with older, problematic servers that are not properly configured.
The amazing part of Safari Integration is that it happens in real time! No need to restart Safari for changes to take effect!
What's more is that Speed Download can now automatically resume Apple Safari downloads that were not completed 100%. Simply drag the .partial Safari file onto the Speed Download main window, or onto the SD dock icon, and watch it resume quickly and reliably.

Now that's just plain cool !
