Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

I did reset Firefox and it seemed to solve the problem! Thanks!

Did this happen when you tried to open Firefox via a double-click on the Firefox desktop shortcut or when you opened a new tab in Firefox with the home page on it?

In case of the former this can happen if you use "Clear history when Firefox closes" to clear Browsing History

• Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] Clear history when Firefox closes > Settings
