If anyone tries to do this in the future, change .../?sort=CREATION_TIME_DESCEND to .../?sortBy=creation_time_descend.

@deltabravozulu is this still working for you ? I can't get back to "Classic Facebook"

@MichaRotstein I don't think you actually need to use "Classic Facebook" to make it work.

BUT I am not 100% sure, to be honest. I was rolling around between a few scripts trying to cobble my own usable one together and I think this one clued me in to the URL variations and so I just wanted to let people know the sort function changed.

I am pretty sure I had this one working but I was annoyed that I couldn't really toggle things in-page (nor could I in the script I wrote--I was a bit lazy with it), so I just went back to the way things were with no scripts at all (aka terrible).
