The command "firefox --safe-mode" is used to launch the Mozilla Firefox web browser in Safe Mode. Safe Mode is a troubleshooting feature that allows you to start Firefox with default settings and certain features disabled, helping to diagnose and fix problems that might be caused by extensions or themes.

When you run this command, Firefox starts with the following features:

1. Default Theme: Firefox uses the default theme instead of any themes you have installed.
2. Default Toolbar Layout: The toolbar and menu layout is reset to the default settings.
3. Disabled Extensions and Themes: All extensions and themes are temporarily disabled.
4. Hardware Acceleration: Hardware acceleration, which utilizes your computer's graphics card to improve performance, is temporarily turned off.
5. Plugins Disabled: All plugins are temporarily disabled.
6. JavaScript Debugging: JavaScript debugging features are enabled.
7. Logging: Logging is active, allowing you to view more detailed information about any errors or issues that occur.

By starting Firefox in Safe Mode, you can determine whether a problem you are experiencing is caused by a faulty extension, theme, or any other customization that you have applied to Firefox. If the issue is resolved in Safe Mode, you can narrow down the cause and take steps to fix it.
