Hello,
I think you can find more help on the English-speaking topics of
http://www.autoitscript.com/forum. But as I see everywhere on french and english forums,
"ce type d'udf ne fonctionnent que sur une page web avec du html et du php" (here is
a sample link), aka FF.au3 can't do anything with a dynamic web page (the HTML source is the only thing AutoIt can work on with this UDF, an Ajax modification is not carried over to the source; of course, it's a dynamic modification, isn't it? ^^).
Sorry for these bad news :-/ But (I think) you can't catch the new inner data of your <div>.
See you !
PS: You should modify your title, it must start with [..], example [..] FF.au3 : Catch ajax div
PS2: I'm not quite confortable with english, sorry
