Forums / Cotonti / Extensions / AJAX parts in plugs

A browser freeze probably means that you are sending your data synch. and not a-synch.
So the browser will wait for an answer (explaining the freeze up).

Maybe your xml anser never comes back? (so a timeout will occur)

What is x?
Is x also located as a field within your form or maybe in the cookies? If it is, then you do not have to send it.. maybe this gives a clash..

TIP:
You really shoud look at the jquery forms plugin..
That plugin is great and it works easy!

So a lot off questions and possibilities..
