With X Rebirth, player-created content used to change the way the game works is called "extensions". In earlier Egosoft games, player-created content is called scripts or mods.
Please note that the use of mods (e.g. Rebirth Workshop items, AKA "Extensions") extensions or save game edits can break games either of themselves, after future game updates, or via conflict with other mods extensions. Consequently, Egosoft are not generally able to support modded/save-game editted games (see here for further details).
Items are preceded by the Rebirth version they where either most recently adjusted or added with.
Mods NZ Wanderer manages a fantastic, up-to-date list of many extensions, and their status, here (on Egosoft's X Rebirth - Scripts and Modding forum).
UNless noted otherwise, extensions are generally added to the Extensions extensions folder in the game's route directory s installation directory ( e.g. C:\SteamLibrary\SteamApps\common\X Rebirth\extensions ).

Extensions can be subscribed to via the Steam Workshop. This offers connivance for the user in that the Steam will manage installation and updating.
