The download manager is overall bad... 1. You can't see download progress in the app. 2. You can't pause or continue download. 3. Your download instantly fails if you close the app. You can help by fixing these issues, if the app is closed pause the download to be resumed later. I look forward to an urgent response and solution to these problems, I just joined the Firefox family so far the experience has been great, it would be a shame if I have to get another browser to handle my downloads.
