Container Tab Sorter από Luthriel

Tired of hunting through a mess of tabs from different containers? Container Tab Sorter is here to help. It's a straightforward extension that does one thing well: it keeps your Firefox container tabs organized automatically by grouping and rearranging them based on the parent container. Moreover, it can optionally sort tabs within each group by their domain, title or the whole URL. There's no need to manually click or confirm anything, as sorting happens automatically upon opening a new tab!
