The in-built browser download manager is not very reliable for download files. It often becomes slow, sometimes fails to resume interrupted downloads, and can cause issues during larger files downloads, and also face trouble to download torrent files.
In this situation, we look for a reliable and professional free download manager that can handle all types of file downloads. For the solution I find out a best free open-source download manager, it's very safe and secure, it's support resume broken downloads, also works with all popular browser integration such as Chrome, Firefox, Edge etc, it's also support torrent and magnet link, which is available for all computer operating system such as Windows, macOS and Linux, and it's available for Android, I am talking about Free Download Manager (FDM), it was initially launched in 2004 by the software development company SoftDeluxe. I am using it for 5 years in Windows, Linux and macOS and still I didn't got any issue on it, it's perfect free download manager for me. I think you could also try it.
