What Simple Tab Groups is

Simple Tab Groups is a Firefox extension for organizing tabs into groups and switching between them. It works across browser windows and can bring the selected window to the foreground when you switch groups. In Manage Groups, you can move tabs with drag-and-drop, sort them, and search or filter them. Tab search, session restore, and workspaces are listed capabilities. You can save tabs, groups, and settings to a JSON backup and restore them later. On Windows, an optional native-messaging host can save backups in any folder. The extension offers a dark theme, colored group icons, and custom icons. It supports Firefox Multi-Account Containers and describes an integration with Gesturefy. Groups can also be imported from backups of the old Tab Groups extension, Panorama View, and Sync Tab Groups. The maker describes it as a way to switch between active and pre-loaded tabs across multiple windows. Simple Tab Groups is free and is licensed under the Mozilla Public License 2.0. Private (Incognito) Mode is not supported. Its listed permissions include access to tabs, hiding tabs, local storage, downloads, sessions, and data for all websites; bookmark access is optional.
