Tab Master 5K replaces your New Tab page with a full-featured tabs, history, bookmarks, apps, extensions, and sessions manager.

Features

Tabs

• Close, pin, and mute tabs from your New Tab page.
• Re-order tab tiles by dragging and dropping them.
• Close all tabs from a specific website.
• Close duplicate tabs, and optionally make them pulsate.
• Manage tabs through icons, the right click menu, or through a table view.
• Search tabs in the top search bar.
• Option to sort tabs by website or alphabetical order, and apply the order to your Chrome window.
• Automatically discard tabs from memory and customize how long they have to be inactive to trigger it.

Customization

• Import any wallpaper as a background.
• Adjust the size of the grid tiles.
• View a screenshot of each tab in the grid.
• Enable screenshots to cover the background of a New Tab page when you hover over a tab tile. You can adjust the strength of the blur and opacity of backgrounds in Preferences.

Session Management

• Session manager built in for saving and restoring your current tab sessions.
• Synchronize your saved sessions, and keep them persistently updated with the current Chrome window.
• Tab sessions can be exported and imported.
• View, sort, and filter your session tabs as tiles in the grid view.

Chrome Management

• Quickly navigate the extension with keyboard shortcuts.
• Undo tab actions by pressing CTRL+Z, or through the context menu while a New Tab page is open.

Contributing

• Install the project dependencies with npm install.
• Start the development environment with npm run dev-chrome for Chrome or npm run dev-firefox for Firefox.
• Load the app directory as an unpackaged extension.
• To build for production, run npm run build-chrome for Chrome, or npm run build-firefox for Firefox.

Building with Docker

For compliance with Mozilla's source code policy, an effort has been made to make the end result of the extension build process reproducible across different environments.

• Ensure Docker is installed and the daemon is running.
• Run ./docker-build.sh <command>. This will build the container if needed and run the command arguments.
  • E.g. ./docker-build.sh npm run build-firefox
