In some instances, Firefox may not remember changes you've made to your toolbar settings or certain other configuration changes.

This article explains how to fix the underlying problem that may result in one or more of the following symptoms:

  • Changes that you made to your toolbars are not saved when you restart Firefox.
  • Changes made to the browser window's size and position are not remembered when you restart Firefox.
  • You cannot save new bookmarks.

Reset Firefox to fix the problem

Firefox's reset feature will reset toolbar preferences and disable add-ons that could be interfering.

Note: When using the refresh feature, your bookmarks, browsing history, open tabs, windows, passwords, cookies and web form auto-fill information will be saved. However, your extensions and themes will be removed and your preferences will be reset. Learn more.

  1. Click the menu button New Fx Menu and then click help Help-29 .
  2. From the Help menu choose Troubleshooting Information.
    If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
  3. Click the Refresh Firefox button in the upper-right corner of the Troubleshooting Information page.
    Refresh 35 Win Refresh 35 Mac Refresh 35 Lin
  4. To continue, click Refresh Firefox in the confirmation window that opens.
  5. Firefox will close to refresh itself. When finished, a window will list your imported information. Click Finish and Firefox will open.
Note: There's also a Refresh Firefox button in the Firefox Safe Mode window, if you can't start Firefox normally. If you are unable to find the Refresh Firefox button on your version of Firefox, you can also do a manual refresh by creating a new profile. See instructions on how to create a new profile.


The above symptoms are usually caused by a corrupted file in your Firefox user data, called localstore.rdf. This file is maintained by Firefox to manage some of your configuration settings.

Another possible cause is a misbehaving Firefox extension.

Fixing the problem

Resetting localstore.rdf

  1. Click the menu button New Fx Menu , click help Help-29 and select Restart with Add-ons Disabled.... Firefox will start up with the Firefox Safe Mode dialog.
    Note: You can also start Firefox in Safe Mode by holding down the shift key while starting Firefox.holding down the option key while starting Firefox.quitting Firefox and then going to your Terminal and running: firefox -safe-mode
    You may need to specify the Firefox installation path (e.g. /usr/lib/firefox)
  2. In the Firefox Safe Mode dialog, select Reset toolbars and controls and click Make Changes and Restart.

You should now be able to customize your toolbar settings and controls, change the browser window size or position, and save new bookmarks, and those changes will be remembered when you restart Firefox.

Disabling extensions

If the previous solution did not help, you can temporarily disable all extensions and then restart Firefox. If the symptoms go away then one of your extensions was causing the problem.
