If you want to completely bypass Winston while using Safari, for example since there is not currently a Winston Safari browser extension, you need to add port 8892 to the HTTP and HTTPS Proxy. You need to have your network system preferences unlocked for this, which most people do.

Here's how:

1) Select Preferences

2) In Advanced, click on Change Settings, then navigate to Proxies and enter the proxy settings there, as follows. Note that it is important for it to be added to Web Proxy (HTTP) and Secure Web Proxy (HTTPS), then select select OK to Apply Settings.
