Grouped — Tab Group Manager by DeveloperAnonymous

Grouped — Tab Group Manager

Safari-style tab groups for Firefox. Organize your tabs into named groups and switch between them — inactive groups are fully unloaded from memory, so only the tabs you're using right now are ever open.

How it works

Unlike Firefox's built-in tab grouping (which just visually groups tabs but keeps them all loaded), Grouped works like Safari:

• Switching groups closes your current tabs and reopens the new group's tabs
• Inactive groups are stored as snapshots — URL lists only, zero memory cost
• Only one group's worth of tabs is ever live at a time

Features

• Create unlimited tab groups with a custom name, emoji, and color
• Switch groups — current tabs are saved and closed, new group's tabs open fresh
• Tab count shown per group so you always know what's waiting
• UI locks during switching to prevent accidental double-switches
• Groups and snapshots persist across browser restarts
• Delete groups with a two-tap confirmation (no accidental deletions)

Permissions

• tabs: Read and manage open tabs
• storage: Save group snapshots across sessions
• sessions: Reserved for future session restore features
