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

Note: If toolbars or toolbar items are missing, see Restore the Menu bar in Firefox and Navigation buttons like back, home, bookmarks and reload are missing.

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

  • You have added, rearranged or removed buttons from your toolbar, but the changes are not saved when you restart Firefox.
  • You have resized or moved the browser window, but the new size and position are not remembered when you restart Firefox.
  • You cannot save new bookmarks.

You may have a corrupt xulstore.json file.

Type about:support in the address bar and press enter. Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox. Locate the xulstore.json file. Then rename or delete it. Restart Firefox.

Reset Firefox to fix the problem

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

Note: When you refresh Firefox, 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 Fx89menuButton, click Help, and select More Troubleshooting Information.
