Recently I have been helping a client set up "lookalike audiences" on Facebook for their site visitors. This is a great way of taking a snapshot of your average visitor profile, and then letting Facebook's slightly creepy data gathering be applied to help you target a highly relevant audience.
In order to map your website visitor data to Facebook's targeting methods, you have to install a tracking pixel. This is a little snippet of code that sits in your website <head> tag, and does the data gathering on your behalf. It's a 2 minute job to find and install this code on most CMS.
To ensure that you've got the code properly configured, Facebook also helps you out by providing a Chrome browser extension called "Facebook Pixel Helper". The purpose of this extension is to allow you to load any site that is supposed to have a tracking pixel firing, and then check if it is actually installed and working properly.
I used the Pixel Helper on this client's site after installing the pixel, and got a message informing me that the pixel could not load. No amount of checking and re-checking could turn up any error with the implementation of the pixel ...
... so what was the issue? Well, it turns out that I had Ublock Origin (an ad blocker) running on my browser. Lo and behold, if I turned on the debug on Ublock, there was a line informing me that Facebook's pixel had been blocked. Pausing Ublock and refreshing the page, then checking the Pixel Helper again informed me that all was working as intended!
So if you're getting an error on Facebook Pixel Helper saying that the pixel will not load, check to make sure you aren't using an ad blocking extension.
