Auto Tab Group von Akila

Auto Tab Group automatically organizes your tabs into native Firefox tab groups based on how you open them.

Features:
- Automatically groups a new tab with the tab that opened it
- Auto-collapses inactive groups so your tab bar stays clean
- Same-domain mode: only group tabs from the same website
- Custom rules: assign a specific name and color to groups from your favorite sites
- Blocklist: prevent specific sites from ever creating groups
- Save and restore tab groups for later
- Ungroup automatically when only 1 tab remains in a group
- Limit the maximum number of tabs per group
- Auto-name groups by domain, subdomain, or full URL
- All settings sync across devices via Firefox Sync
