TABDROP от Closly Friend

TABDROP groups tabs in the current Firefox window into native Firefox tab groups. It matches tab domains against editable local rules, creates
clear group names, and lets you undo the last grouping action.

Features:
- One-click grouping for the current window
- Automatic grouping for newly opened tabs, if enabled
- Editable rules, group names, colors, and priorities
- Domain fallback for sites without a custom rule
- Pinned tabs are skipped
- Settings stay in Firefox local extension storage
- No accounts, analytics, ads, or remote tracking

The support section includes optional donation wallet addresses and a GitHub link. All features are free.
