It depends on how the extension is designed and which storage API is used.  
If it is a WebExtension and it uses [storage.local](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage/local), then the settings is stored in [Profile Folder](https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data)/profile.name/browser-extension-data/{extensionid}/storage.js  
However, an extension can also use [storage.sync](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage/sync) which stores the settings in the cloud for example, and unfortunately you can’t have access to it.

or any of the DOM storage APIs etc. It would really help to state your intent, too.
