Tab Sniper is a browser extension for Firefox and Chrome that helps you wrangle browser tab chaos. When you have dozens (or hundreds) of open tabs, Tab Sniper gives you the tools to quickly find, organize, and close what you don’t need.
Features
- Filter tabs by URL or title text in real-time
- Group tabs by hostname or custom categories
- Audio filter to find tabs playing sound
- Keyboard navigation for power users (Arrow keys, Enter, Tab)
- Bulk close all filtered tabs or entire groups with one click
- Category management to organize domains into logical groups
- Keyboard shortcut (Ctrl+Shift+B / Cmd+Shift+B) to open the popup

Why self-hosted? These extensions are distributed directly rather than through the Chrome Web Store. Google requires a mandatory $5 “developer fee” to publish extensions—a predatory tax that creates unnecessary friction for open source developers sharing free tools. Firefox Add-ons, in contrast, remains free for developers.
