Untabit от DudeSoft

Untab it! One shortcut to pop the current tab out into its own window — and the same shortcut to put it back.

HOW IT WORKS • Press Alt+U (Ctrl+U on macOS) or click the toolbar icon • A tab with siblings pops out into its own window • A tab alone in its window merges back where it came from, at its old position • If the original window is gone, it joins the most recently used window instead

NO RELOAD The tab is moved, not reopened: video keeps playing, scroll position and form state survive.

PRIVACY No data access, no tracking, no analytics. The only permission is "storage", used to remember where a tab came from — session-only, cleared when the browser closes, never written to disk.

The shortcut is rebindable at about:addons → gear → Manage Extension Shortcuts
