This extension uses the existing proxy settings in Firefox. It simply adds a toggle button to the toolbar.
The Firefox proxy settings are in: [Options > General > Network Settings > Configure Proxy Access to the Internet].
To change the proxy configuration or the default on/off state:
Disable the extension.
Change the Firefox proxy settings.
Re-enable the extension.
The proxy will be in the default state (that you set via the steps above) when you start Firefox.
The add-on must be allowed in Private Windows to work (FF 67+).
Advanced note: The extension resets the proxy setting on startup. If there are no other extensions modifying it, the setting will revert to the user-set value. To learn more about how Firefox manages setting changes, see Firefox BrowserSetting (MDN).
