Possible false positive with Adobe Test & Target rule (Facebook CDN)

[steveluscher]

Description

I have received a report of Ghostery blocking this resource. The block was made according to the ‘Adobe Test & Target’ rule:

https://static.xx.fbcdn.net/rsrc.php/v3/yM/r/MBOX6JqmhhS.js?_nc_x=yIsXPYraEd4

This is a resource from the Facebook CDN that, like many others like it, is critical for the operation of the website. Do you see anything about that file or that URL that would trigger that rule, and do you believe this to be a false positive that can be fixed?

Expected Behavior

Resource should trigger no rule.

Actual Behavior

Resource triggers the ‘Adobe Test & Target’ rule; gets blocked.

Steps to Reproduce

1. Use Ghostery.
2. Load the Beta version of facebook.com.
3. Observe that https://static.xx.fbcdn.net/rsrc.php/v3/yM/r/MBOX6JqmhhS.js?_nc_x=yIsXPYraEd4 triggers the ‘Adobe Test & Target’ rule; gets blocked.

This looks like a false positive. Adobe Target uses something called mbox which we are catching in your Facebook CDN pattern. I'll get this cleaned up on our end. Thanks for reporting.
