Facebook Pixel Add-On

When you use a Facebook pixel on your site, it will cause browser caching warnings in PageSpeed, GT Metrix and other performance testing tools: 

The Facebook Pixel Add-on resolves this by storing the necessary files on your server, so browser caching will be applied to them. 

Activate the Facebook Pixel Add-On

Go to the  Add-ons tab in WP Rocket and simply toggle the Facebook Pixel Add-on to on:

We target these files and their variations:

https://connect.facebook.net/{{locale}}/fbevents.js
https://connect.facebook.net/signals/config/{{app_id}}?v={{version}}&r={{release_segment}}
https://connect.facebook.net/signals/plugins/{{plugin_name}}?v={{version}}
https://connect.facebook.net/{{locale}}/sdk.js

The local files will be stored in the  /wp-content/cache/busting/facebook-tracking/ folder.

Note: the recommended Facebook and WooCommerce plugin integrations are supported, but Google Tag Manager is not.
