Allowing users to edit proxy settings can help them bypass filtering. It is therefore recommended that you prevent users from changing the proxy configuration.
To disable the proxy settings on a Mozilla Firefox:
- Double-click Mozilla Firefox icon.
- On the Mozilla Firefox window, click on Tools then click Options.
- Click Advanced.
- Click the Network tab then click on the Settings button.
- On the Connection Settings window, ensure that the No Proxy option is selected. Then, click on the OK button to apply the changes.
Note: The latest versions of Firefox trust the internal certificate store by default. This is for legacy versions of the browser only.
