errors in pingdom

Hi there,

I still get these two errors in pingdom tools. I thought this plugin should fix these?

C75-Remove query strings from static resources
B83-Specify a Vary: Accept-Encoding header

it’s these two which gives the errors for both problems:
staticxx.facebook.com/connect/———–.js?version=42
fontawesome-webfont.woff2?v=4.5.0

Thanks
