Tab Manager - Duplicates & Merge | OpenTabs — OpenTabs

OpenTabs is a privacy-first new-tab workspace that helps you see, organize, and act on your open tabs without sending your browsing activity to a remote service. Tab grouping and ranking run locally in the extension, so your tabs stay in your browser.

FEATURES

• View open tabs from multiple browser windows in one place
• Group tabs automatically by website
• Close tabs directly from the dashboard
• Find and close duplicate pages
• Merge tabs from multiple windows
• Capture your daily focus with tasks and nested steps
• Keep task progress after refreshing the page
• Launch frequently used web apps
• Add configurable cards for weather, calendars, bookmarks, markets, topics, and more
• Export and restore your configuration with a portable config string

Core tab management and Focus features work without an account. An account is only needed for community actions such as publishing or liking shared packs.

OpenTabs is free and open source. It is designed for a fast new-tab experience, with local processing for tab organization and background updates for optional information cards.

Available for Chromium-based browsers and Firefox.
