kTab Manager от Jerome Saiz

kTab Manager shows all your windows and tabs in a clean, color-coded view. While it works perfectly with the mouse, its core feature is keyboard-first navigation: hit Option+T, type a few letters of a domain or tab title, arrow down, and you're there.

Other cool features

• Group tabs by domain (all YouTube tabs together, all GitHub tabs together) or by browser window
• Mute / unmute tabs individually or all at once with a single click
• Close all duplicate tabs in one click, keeping one per URL

Privacy
kTab Manager only requests the tabs permission. It makes no external connections and collects no data whatsoever.
