What is the primary purpose of implementing a Facebook Pixel Helper extension in a web browser?

The primary purpose of the Facebook Pixel Helper extension is to verify and troubleshoot the correct implementation of the Facebook Pixel on a website. The Pixel Helper is a tool that allows you to see whether the Facebook Pixel is installed correctly, if it's firing correctly, and if the custom events are set up as expected. For example, if you install the Pixel on your website and then visit a product page, the Pixel Helper will indicate whether the 'PageView' event is firing and whether any custom events you've set up for that page (like 'AddToCart' or 'Purchase') are also being triggered correctly. It also helps identify errors, warnings, and suggestions for improving the Pixel's implementation, ensuring accurate data collection for ad tracking, optimization, and retargeting.
