Tab Groups List is a free Chrome extension developed by Marek Mauder in the Browsers category, specifically under Add-ons & Tools. This simple yet practical extension displays a list of all tab groups from all browser windows in a convenient popup. By clicking on a group, users can quickly navigate to that specific tab group, focusing on the first tab within it and its respective browser window if necessary.

The primary aim of Tab Groups List is to aid users, particularly those with numerous tab groups spread across multiple windows, in easily locating and accessing specific tab groups. The extension optimizes the display of tab groups by showing them in 1 to 3 columns based on the available space, ensuring maximum visibility without the need for scrolling.
