I use a download manager because when I’m directly downloading large files Firefox gets mad. I also like the feature of batch downloads. What do you guys use?

I’ve tried a bunch of different download managers, but none have done exactly what I want. Currently I am using aria2 with Persepolis, but the project doesn’t seem like it is being updated. Is there any tool that:

• Is open source
• Can batch download files from a list of URLs
• Intercept Firefox/browser download manager

Optionally

• Batch download from premium file sharing hosts like rapidgator
• Download youtube videos (I have only been able to accomplish this with website or aria2 with yt-dlp)

I’m looking at IDM (Internet Download Manager) but it is not open source and I would have to look at a crack or free trial abuser thingy. This is not a deal breaker but I would much prefer to run something open source.
