Firefox Update Error

So, on one of my computers, I've had problems updating Firefox. When going to Help > Check for Updates, I'd get the error: "".

Well, after some research, I found that the app.update.url setting in the Firefox configuration was wrong, or at least pointing to something invalid. My original update url was:

If you're having that problem too, then try this:

  1. Open a new tab
  2. In the address bar, type about:config and hit enter
  3. In the Filter, type app.update.url
  4. Double-click this property
  5. In the dialog that pops up, enter the following path (which is almost identical):

    Note: when you copy and paste this, make sure you get all of it. Easiest way is to right-click the URL and click 'Copy Link Location'.

    Firefox screenshot showing the about:config window and appropriate options
  6. Click Ok
  7. Try Help > Check for Updates
Voila! Now you should be able to receive automatic updates for Firefox.

Worked for me too. Not sure why it was still broken after downloading the latest version manually, but it was. Maybe we can get this upstream??? Anyway, thanks!
