Flashget as my download manager.
I also use Flashgot add-on with Mozilla Firefox. I always use Flashget to download my files. It downloads from multiple downloads. I also have Flashget scan the download with Avast so I am guaranteed the download is not corrupt.
I was looking at some of the settings in about:config in firefox 3.01 and wondering what some of the setting meant in the lines of browser.download section and wondered if there were any tweaks to increase the download rate of anything you wish to download from a site. I'm not looking for improvments that exceed what a website can accomedate but if its even possible to tweak the download maneger in order to create more connections to the site or break the download into sections that later can be put back together.
