So I installed this tool and it works well for me. However there was a bug I was for quite a while not able to track and resolve.
My Firefox was not able to load to facebook comments form properly (it always ended up just with the Like button and no other functionality so far), while in Chrome, IE and Opera it was OK. When I loaded same page in clean Firefox under different user account on my desktop, it loaded just fine. After a while I tracked the issue to be caused by Adblock add-on in Firefox.
So beware ladies and gentlemen, your anti-ad tools could disable the good stuff too.
