SwiftDL Integration by Harsh Singh

SwiftDL Integration connects Firefox to SwiftDL, a free and open-source download manager for Windows, macOS and Linux.

Browsers download every file over a single connection. SwiftDL splits each file across up to 32 connections and keeps all of them busy, so downloads from servers that limit each connection finish many times faster. Progress is saved every second, so a crash, a closed laptop or a dropped connection never means starting over.

What the add-on does:

Sends downloads you start in Firefox to SwiftDL, with the site's cookies, so downloads behind a login keep working.
Adds a Download video button to video players. On YouTube and other video sites, pick a quality in SwiftDL, from 4K to audio only.
Sends magnet links and .torrent files to SwiftDL's built-in torrent client.
Hold Alt while clicking a link to let Firefox download it instead, or turn SwiftDL off for a single site from the toolbar button.
Requires the SwiftDL desktop app, free from https://swiftdl.harshhh.me. The add-on talks only to the app on your own computer (native messaging); nothing is sent to any server.

Does this add-on require payment, non-free services or software, or additional hardware? No. (It needs the SwiftDL desktop app, which is free and open source.)
