USERSCRIPTS and EXTENSIONS actual database for Duolingo [UPD

This post was originally written by U_S_Ee_R for Duolingo forum.

Many of userscripts and addons are created several years ago and no longer work due to site changes. Everything presented here is checked by me and should work with the latest version of the Duolingo site. I have been updating this list regularly since June 14, 2020.
