Clear download list in Firefox

Firefox by default never clears the download list automatically. If you wish change the way Firefox works so it will clear the downloads either automatically upon download complete or when Firefox closes following the next steps.

  1. Type about:config in your address bar
  2. Search for browser.download.manager.retention
  3. Set its value to either 0, 1 or 2 depending on how you Firefox to behave

0 indicates that the download should be removed upon completion.
1 indicates that completed and canceled downloads should be removed when Firefox closes.
2 indicates that downloads should never be removed automatically. (default)

Force Firefox 20 to use the old download manager

Mozilla released Firefox 20 a few days ago that came with various new features such as:

  • a new per-window Private Browsing feature
  • a new download manager
  • the ability to close unresponsive plugins without the need to restart the browser

Sadly my personal opinion about the new download manager feature isn’t very good. The new manager seems to be very user unfriendly and from what I can see there isn’t an option in the settings to clear a download file from the history automatically after the file has been downloaded. Luckily there is an easy solution for this for those that would like to revered back to the old download manager design.

  1. Type about:config in your address bar
  2. Search for browser.download.useToolkitUI
  3. Set its value to true

Now everytime you download something the old version of the download manager will start instead of the new one.


If you also want to remove the new download button that was added in this new version simply right click on the bar, click Customize… and drag and drop the button you don’t want into the customize toolbar list that will appear.
