Forks and alternatives

1 other plugin uses the same ID as this one. Every Zotero plugin carries an ID, a name tag Zotero uses to tell plugins apart. These 2 plugins carry the same one, because people copied Codex Bilingual Reader to make their own versions and kept its ID.Show what this means
  • You can only have one. Zotero sees them as the same plugin.
  • Installing another replaces it. If you install one of the others, it takes this one's place.
  • Check what you install. Several share this plugin's name, so make sure the file comes from the one you meant.
