For 2, one of the few pieces of Windows software that I haven't been able to replace in Linux is GetRight. Many HTTP servers support downloads starting at an offset from the beginning of the file, and GetRight uses that to allow download pausing and resumption.

It was a real life saver back when I had an extremely flaky Internet connection.

EDIT: Thanks for all the suggestions, I'll definitely take a look at them. Simply resuming downloads is why I initally started using GetRight, but it also came with a bunch of other useful tools that I came to rely on. While I've been able to replicate some of the basic functionality with individual browser plugins or programs, I haven't seen anything that integrates it all so well, with such a smooth interface. I haven't looked for a long time, though, so maybe one of your suggestions will be the one!

Firefox does that out of the box.

Wow, getright! That's a throwback. I used that in the 90s.

On linux I use aria2c for similar tasks. It can resume http downloads, as well as split them up into multiple threads for faster downloading.

It's cli-based and powerful (therefore perhaps a bit confusing at first), but there are UIs for it as well for a more get-rightty experience.

I think jdownloader also has some application here, though it's mostly for getting things from those ad-filled file hosting sites frequently used by those on the high seas

Why would you multithread it except for heaving mutiple paths of entry to your home connection or you are getting a throttle from the file hoster?

Basically that. I don't do it much anymore, but it used to be helpful.

Have you tried JDownloader?
