one by one with the following steps: 1. 2. Find the download record you want to remove in the list and click the Remove link. Removing a record instructs Firefox to forget what it knows about that specific download only. If you download the same file again, Firefox creates a new record in your download history. Removing all download records at once If you're no longer using any of the records in the Download Manager, you can remove them with the following steps: 1. 2.
