I think this is a fabulous utility, thank you a lot for providing it!

I do have one problem and a few questions:
When I want to duplicate a tab, instead of opening next to the current one, it opens as a last tab on the right, despite in the advanced settings having the default setting extensions.tabutils.openDuplicateNext;true

What is the difference between a protected and a locked tab?

This review is for a previous version of the add-on (1.5.1).
