The prefs.js file, located in the profile folder, is used by Firefox, Thunderbird, Mozilla Suite, and other Mozilla-based applications to store preference settings. For instance, when you create a new e-mail account in Thunderbird, the account name and server settings will be stored in the prefs.js file in your Thunderbird profile folder. Likewise, if you use the application's user interface (dialog boxes) to change preference settings from their default values, these will be written to prefs.js. Some extensions also store their settings in prefs.js.

Although prefs.js is a plain-text file that can be easily viewed with a text editor, it is recommended that you do not attempt to edit this file directly since you can damage your profile if you make any mistakes. Instead, it is better to modify your preference settings using one of the standard methods. Also note that whenever the application is started, entries in prefs.js will be overwritten by a possible user.js file.
