# Firefox

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 properly on your current mac machine.

Check out macOS Guideline:

[macOS](/~/revisions/CTFzuwrlmsieJaiDVRDD/debug-devices/macos.md)
{% endcontent-ref %}

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

### 2. Set Proxy on Firefox

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