The Firefox browser allows users to edit and create new styles on their web pages using the Style Editor. The Style Editor provides you with a space to edit and view the CSS used on the site. You can create your own CSS file or import it from your system. The Style Editor also allows you to save a CSS file that can be used in the development source code.

Benefits of the Style Editor:

The Style Editor is just an in-built CSS editor in the Firefox browser. It has the following benefits:

• Color Coded: The CSS code displayed in the Editor is properly colored coded. This makes the CSS code more appealing to look at by the developers, and without this color code, the developers may not be as productive as the other way around.
• Import and Export: The Editor also allows you to import styles from your system; this is a very good option as styles can be directly checked in the browser itself. You can also save the styles you edited or new styles you created in your system, which can be used directly in the source code.
• Easy Navigation: The UI is simple and is basically separated into 3 sections. The sections are the style list, the main editor, and the rules of the current styles. This makes the developers easy to navigate around.
