Chrome Extension Support

Electron only supports loading unpacked extensions (i.e., .crx files do not work). Extensions are installed per-session. To load an extension, call :

Loaded extensions will not be automatically remembered across exits; if you do not call loadExtension when the app runs, the extension will not be loaded.

Note that loading extensions is only supported in persistent sessions. Attempting to load an extension into an in-memory session will throw an error.

See the session documentation for more information about loading, unloading, and querying active extensions.
