Firefox error - document.all undefined (WebUIValidation.js)

I created a simple ASP.Net application where the first page accepts the entry and clicking the button redirects the user to the next page.
This works in all other browsers (IE, Opera, Safari), but nothing happens in Firefox. There is no event generated when the button is pressed, and no postback occurs.

A look at the Firefox error console showed me this error:

document.all - undefined
http: //xxx/aspnet_client/system_web/2_0_50727/WebUIValidation.js
Line: 30
Line: 85

Functions in which this error occurs in WebUIValidation.js:

function ValidatorHookupControlID(controlID, val) {
    if (typeof(controlID) != "string") {
        return;
    }
    var ctrl = document.all[controlID];

....

function ValidatorGetValue(id) {
    var control;
    control = document.all[id];

....

Please, help!!!
