Better Tab Groups — Mzero

Better Tab Groups supercharges Firefox's native tab grouping with intelligent automation features that keep your browser organized effortlessly.

Automatic Duplicate Merging:
Never create duplicate tab groups again! When you try to create or rename a group with a name that already exists, the extension automatically merges them together, keeping your tab organization clean and consistent.

Smart Domain Grouping:
Get instant suggestions to group tabs from the same website. Click the extension icon to see which domains have multiple open tabs, then group them with one click. The extension intelligently detects existing groups with matching names to avoid duplicates.

Auto-Group Rules:
Set up rules to automatically organize tabs as you browse. For example:
• Send all YouTube tabs to a "YouTube" group
• Auto-group all GitHub pages into a "Dev" group
• Organize Google Docs into a "Docs" group

Customizable Settings:
• Toggle auto-merging on/off
• Adjust debounce timing to control when duplicate detection happens
• Manage all your grouping rules from an intuitive popup interface
