fastget Download Catcher by Muhammad danish

fastget speeds up downloads by splitting each file into several parts and
downloading them at the same time, then joining them back together. It can
pause and resume downloads, keep a download list, limit total speed, and let you
choose where each file is saved.

How it works: this extension catches a download starting in Firefox and hands it
to the fastget app, a small free, open-source program that runs on your own
computer and does the actual downloading. You install the app once (an installer
sets everything up, no command line). Without the app, the extension cannot
download on its own.
Requirements:
- Windows (the fastget app is currently Windows-only).
- The free fastget app, installed from the link on the project page:
https://github.com/alphaxt/fastget

Privacy: everything stays on your computer. The extension sends a download's URL,
name and (optionally) that site's cookies only to the local app, over your
computer's internal loopback connection. Nothing is sent to the developer or any
third party. There are no trackers. See the privacy policy inside the extension
(privacy.html) or on the project page.
