Simple Tab Groups is a highly rated, open-source browser extension primarily built for Mozilla Firefox designed to completely eliminate tab clutter. Unlike standard, native browser tab groups that merely color-code or bunch tabs together on your screen, Simple Tab Groups works like a workspace manager. It hides all other tabs completely, leaving you with a clean browser interface dedicated strictly to your current task. Core Features
Total Tab Hiding (Workspaces): When you switch to a specific tab group (e.g., “Work,” “Shopping,” or “Finance”), all other tabs vanish from your tab bar. They are safely stored in the background and instantly reappear when you switch back.
Firefox Multi-Account Containers Integration: You can link specific tab groups to dedicated Firefox Containers. For example, your “Social Media” group can automatically open all links in a separate sandbox, allowing you to log into multiple accounts on the same website simultaneously without mixing data.
Automated Tab Rules: You can configure regex or string rules so that specific domains (like github.com or youtube.com) automatically open inside their designated tab group rather than your active workspace.
Data Security and Auto-Backups: The extension protects your sessions by generating local auto-backups in JSON format. If your browser crashes or updates unexpectedly, you can restore your exact group setups with one click.
Deep Customization: Features advanced keyboard shortcuts, tab-searching across all groups, group notes, and full integration with mouse gesture extensions like Gesturefy.
