## ❌ Old Solution (Proxyman v5.18.0 or ealier)

In order to intercept HTTPS traffic from Firefox, it requires extra steps to install Proxyman CA into Firefox's Trust Store.

### 1. Install Proxyman CA on macOS machine

Before installing Proxyman CA on Java VMs, we have to install it properly on your current machine.

Check out macOS Guidelines:

{% endcontent-ref %}

If you've done this step, you can skip to the next step.

### 2. Set Proxy on Firefox

* Open Firefox's Preferences panel (CMD+,)
* Search Proxy and open the Proxy Settings
* Select Auto Use System Proxy or manually hardcode the Proxy IP and Port
