I am using the telerik controls (v 2013.3.1015.45) for my project and it is working fine on IE all version. but it is not working on firefox 26.0 . I got following error.
I have tried the suggested solution on site.
1.Added the Entry in web.config file.
2.Removed the “RadScriptManager” and added the “ScriptManager”.
