Components added in this way are invisible to users and cannot be managed through the Firefox add-ons manager. What's worse, though, is that these components don't have a mechanism for specifying the versions of Firefox with which they are compatible, leading to poor integration and instability as users upgrade their Firefox installations.", "sections": [{"id": "Simple_migration", "title": "Simple migration"}, {"id": "Automatic_installation", "title": "Automatic installation"}, {"id": "JavaScript_C-Types", "title": "JavaScript C-Types"}], "slug": "Migrating_raw_components_to_add-ons", "review_tags": []}
