The Download Manager uses an SQLite table to keep track of downloads in progress as well as queued and past downloads.
The table is kept in a database file named "downloads.sqlite", in a table called "moz_downloads". The current database schema version is 8.
This information is available using
nsIDownloadManager methods to retrieve
nsIDownload objects for each download entry; however, if you feel like poking directly into the table, you can do so using the Storage API.
