UPDATE: we've been told by a fb user this is working just as easy with chrome ;)

TECH:
Microsoft Silverlight (plugin) thats what makes the adverts update on facebook, so they change, even if you sit on the same page, the plugin also lets you re-arrange your photos. With that, in turn it'll let you update code in real time (even though its not saved to facebooks servers)
IE. without silverlight you would have to Edit the page save it & then refresh.. that refresh would loose all saved changes & load the unmodified page from fb..

HISTORY:
So how did i work this out?  what's my sources?
I used this same concept for 2 years adding "Follow This Blog" widgets to newly made blogs that only offered the G+ Followers button and not the blogger widget
I only looked into fb code due to the troll blocked in the video   ;)
