I am supporting a web form .net application and I have found out that some of the JavaScript has been deprecated using Internet explorer by using the Internet explorer web developer tools. I have now used the Firefox browser and the application seems to work for what I have tested so far. 

Before I place the new version of the application into production, I would like to know what JavaScript features are currently obsolete and/or may be deprecated in the near future.


Due to that fact, would you tell me and/or point me to urls (links) that will tell me what JavaScript items are obsolete and/or deprecated using the Firefox browser?

[HttpPost]
public ActionResult Create(string street, string city, string state, string zip)
{
    Geocoder geoCoder = new Geocoder(street, city, state, zip);
    ViewBag.GeoCodeMsg = string.Concat("Address confidence is ", geoCoder.Address.Location.Confidence);
    return View();
}

<input type="submit" name="validateAddr" value="Verify Address" class="btn btn-default" 
onclick="location.href='@Url.Action("ValidateAddress","ICSProfile",new { street=Model.Street, 
city=Model.City, state=Model.StateProvince, zip=Model.Zipcode })'" /></li>
