How to Reset Firefox Browser
To reset the Firefox browser, you can follow these steps:
Open Firefox and click on the Menu button in the top right corner of the window.
Click on the "Help" option in the menu and then select "Troubleshooting Information" from the submenu.
In the Troubleshooting Information page, click on the "Reset Firefox" button.
You will be prompted to confirm the reset. Click on the "Reset Firefox" button again to confirm.
Firefox will close and reset itself. When it reopens, it will be in its default state with all settings, extensions, and themes reset to their defaults.
Note: Resetting Firefox will not affect your bookmarks, history, or saved passwords. It will only reset the settings and preferences that you have changed.
