Hello,

I am trying to reset my password for Firefox sync with no success. When i enter my email address and hit "next" i get "Unexpected error". I don't want to create a new account with a different email address.

Any help is appreciated.

Hello jc_denton,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.

Note: After resetting Firefox, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.

To Reset Firefox:

  1. Open the Troubleshooting Information page using one of these methods:
    • Click the menu button New Fx Menu, click help Help-29 and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
    • If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
  2. At the top right corner of the page, you should see a button that says "Reset Firefox" that looks like this: Button reset. Click on it.
  3. Firefox will close and reset. After it is done, Firefox will show a window with the information that is imported.
  4. Click Finish and Firefox will reopen.

Did this fix the problem? Please report back to us!

Thank you.
