Put tab groups away and restore them later exactly as they were: same name, same colour, and every tab's Back button still working (up to 50 pages a tab). See every window, group and tab on one page or in Chrome's side panel, spot duplicates, and search every page in each tab's history. Restored tabs load only when you click them. Free, with no sign-up, ads or tracking. Optional Pro adds sync through your own Google Drive, daily backups and tab sleep.
