Mozilla Firefox add-on

Charles requires an add-on in Firefox to autoconfigure Firefox's proxy settings. Charles will automatically prompt you to install the add-on when you run Charles. If the add-on is not automatically installed, you can manually activate Mozilla Firefox Proxy in the Proxy menu. Alternatively you can download and install the add-on manually.
