    If you want to reset your Firefox browser to its default state, first, start the browser. Then press the menu button (three lines) in the upper right corner, and at the bottom, you will see the Help option. Click on it and choose More troubleshooting information. There you will find the Refresh Firefox button, click it and confirm your choice, after which Firefox will restart with default settings. This method uninstalls extensions and custom changes but retains the major data, such as bookmarks and passwords, thus giving you a fresh browser environment.
