What Simple Tab Groups is
Simple Tab Groups is a free Firefox extension for organizing tabs into workspaces and switching quickly between groups. It works across multiple browser windows and can bring the selected window to the foreground when changing groups. In Manage Groups, tabs can be moved by drag-and-drop, sorted, searched, or filtered. The extension supports tab search, session restore, and workspace-style grouping. Tabs, groups, and settings can be backed up and restored through a JSON file; on Windows, an optional native-messaging host can save backups in any folder. Appearance options include a dark theme, colored group icons, and custom icons. It supports Firefox Multi-Account Containers and describes Gesturefy integration. Groups can be imported from backups of older tab-group tools. The Free plan costs nothing. Private (Incognito) Mode is not supported, and listed permissions include access to tabs and data for all websites.
Good
- Cross-window group switching
- Drag-and-drop, sorting, and tab filtering
- JSON backup and restore
- Dark theme and custom group icons
- Firefox Multi-Account Containers support
Watch out
- Private (Incognito) Mode is unsupported
- Windows-only host for any-folder backups
- Requires broad listed browser permissions
Who it suits
It suits Firefox users who manage many tabs across projects or browser windows and want searchable groups with backup and restore. It is less suitable if private browsing support is required.
Verdict
Simple Tab Groups provides structured tab workspaces, searching, cross-window switching, and JSON backups at no cost. Its main limitations are the lack of private-mode support and the Windows-specific backup host.
