Facebook Pixel

On which page in the script can I install the Facebook Pixel code so it works.

I already tried on index.html in templates base, but the Facebook pixel helper says 'no pixels found ...'

what exactly is facebook pixel? Not knowing what it is, the only two places i can think of that you could probably use the code is in a 'text' block on whatever page you want - or use the _header.html page in the template folder

after looking it up - if using 7.2 or greater - just paste it in the admin section - settings - basic settings - scroll down to the injections section and paste in the head injection block. But - there is already an implementation for google analytics which may be a bit better than the facebook pixel. seems like they do the same thing (track visitors to your website and what they do). I personally do not trust facebook that much for them to track my visitors.
