Sort Selected Tabs — DeKay

Sort Selected Tabs does exactly what it says - no extras, no bloat.
Simply select multiple tabs in Firefox, right-click, and choose how to sort from either tab name, domain, URL, file name or access time.

Unlike other tab managers that often sort all your tabs or don’t work as expected, this add-on only affects the tabs you’ve selected - nothing more, nothing less.

• Works in normal, private, and container tabs.
• Keeps tabs in their original groups and containers
