Any chance of adding tab set bookmarking?

The official Pinboard extension had this and some Chrome extensions offer it but as far as I can tell there is no current Firefox extension that is compatible with Quantum that offers this.

Pinboard WebExtension [sic] has this option. I use it in combo with Pinboard+.
