Configuring Mozilla Firefox to Use a PAC File
To redirect your web traffic to the Zscaler cloud, configure your browser to use a PAC file. A PAC file is a text file that directs a browser to forward traffic to a proxy server before going to the destination server. The Zscaler service hosts a default PAC file that uses geolocation technology to forward traffic to the nearest Internet & SaaS Public Service Edge. To learn more, see Using Default PAC Files to Forward Traffic to Internet & SaaS.
The browser version used in this example is Mozilla Firefox 94.0.2.
To configure Mozilla Firefox to use Zscaler’s PAC file URL:
Copy the default PAC file URL from your Admin Portal:
- Go to Infrastructure > Internet & SaaS > Traffic Forwarding > Hosted PAC Files.
- Copy the URL of the Proxy PAC to your clipboard.
- Open Mozilla Firefox, open the menu, then click Settings.
- Under the General section, scroll down to Network Settings and then click Settings....
The Connection Settings window appears.
- In the Connection Settings window, select Automatic proxy configuration URL and paste the PAC file URL that you copied from the Admin Portal.
- Click OK to save the configuration.
