Keeping Tabs is a lightweight Firefox extension that automatically numbers your unpinned tabs and enables lightning-fast keyboard navigation. Why Keeping Tabs? Built specifically for Zen Browser users frustrated with pinned tabs taking up the first keyboard shortcuts (Cmd+1-8). This extension solves that by:

Smart Numbering: Only numbers unpinned tabs (1-9), ignoring pinned tabs
Separate Navigation: Use Cmd+Option+1-9 for pinned tabs
Visual Clarity: See tab numbers directly in page titles
Clean Design: Max 9 numbered tabs to keep you organized

Monitors all tab events 2. Filters out pinned tabs 3. Numbers the first 9 unpinned tabs 4. Updates titles in real-time Perfect For
