So, all other functions on Facebook work for you? Does it happen if you "browse anon" in Chrome?
Do you have IE10? Removing that UPdate isn't a big deal. It isn't like it used to be!
If everyone is having the problem, and you all have IE10, then what do you do? If you are all having problems, and only some have IE10, then it is facebooks problem and let them know.
I am 100% certain that IE10 is burning in the wild, and if you do a search for the NEW INTERNET not working, it is IE10 that everyone is moving from. There isn't a corporate organization anywhere with IE10 functioning in production. I would like to hear if there is, and how many seats they have!
BTW, Chrome and IE use the same framework to fetch/browse the internet.
I am sorry if this is not going the direction you had anticipated.
