More Configuration

Your firefox settings are stored in your Profile folder. To know location of your profile folder, enter about:support in your search bar. Under the Application Basics table search for the Profile Directory entry

Refer this post to know which files store what data. The main ones to consider are:

File	Purpose
places.sqlite	All your Firefox bookmarks and lists of all the files you’ve downloaded and websites you’ve visited
bookmarkbackups/	Folder that stores bookmark backup files, which can be used to restore your bookmarks
extensions/	This folder (if exists), stores files for any extensions you have installed
permissions.sqlite, content-prefs.sqlite	Site-specific preferences and permissions (like allowing popups, zoom levels etc.) on a site-by-site basis
prefs.js	Stores customized user preference settings, such as changes you make in Firefox Settings dialogs and in customizing toolbars
key4.db, logins.json	Your passwords are stored in these two files. Refer here for more info

Extensions

I’ve stored my list of Firefox extensions that you can download from the add-ons page

Bookmarks

I’ve exported my list of bookmarks as an HTML file. To enable bookmarks being saved as HTML file, visit about:config in search bar and set the browser.bookmarks.autoExportHTML property to true

Tabs

I use the Simple Tab Groups extension to manage browser tabs in Firefox. It backs up your tabs periodically into within Downloads folder under folder names start with STG-backups-

I’ve stored my list of cookie-exceptions stating site whose cookies aren’t being deleted when browser closes
