Works just as advertised.

This add-on checks your download history every 30 seconds, even when you’re not downloading anything. If you’re looking for an alternative, search for “Download Auto Resumer.”

This is garbage why it is even here taking space.

Garbage. Always comes up with 'NETWORK ERROR' and retries 10 or 20 times but as soon as I manually click on the Retry button in the download panel it starts again. Why the hell upload something when you don't test it.
