Note: New versions of Firefox no longer display a download window.
Remove that pesky download window that appears after downloading a file by adding the Firefox Download Statusbar Add-on
to your browser. Alternatively editing the about:config settings as
shown below can also disable this window from being displayed.
- Open a new tab in Firefox.
- In the address bar type: about:config
- Locate browser.download.manager.showWhenStarting by copying and pasting the bold text into the Filter box.
- Double-click the name or value to change the value from True to False. Once done close the tab.
