I encountered a problem with some client machines that use Firefox version 24ESR and IE8. Ajax requests of aspx pages from Firefox are getting the following error from the iis server (iis version 7.5):

Bad Request - Request Too Long HTTP Error 400. The size of the request headers is too long.

From analyzing the request that was sent to the server, I saw that the request consist of only the viewstate of the aspx page. I tried to disable the viewstate for one page and the server got the request correctly.

I do not encounter any issues on these laptops with postback requests from Firefox or when running the same application with IE8.

Sometimes that means that the page address sent is loo long. Check the link address you are using. I can't help you further and will send for more help.
