    I have this very weird issue.

    Setup: I have jquery 1.10 reference in the master page of my form.  I'm writing a SharePoint 2010 visual web part that contains a RadAsyncUpload (2013 q2).  I also have Script References in my page to:
     <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
    <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

    Problem:  For whatever reason after the page is posted back, I get the error "addback is not a function" whenever I try to upload a file.  This issue happens in Firefox but not in IE (it works completely fine in IE).  Prior to the user posting the page, the upload works fine in FireFox, it's JUST after a postback has already occurred.

    Again, this problem only exists in FireFox and not IE (I can't test it out in any other browsers because my current environment is locked down to just those tow browsers)

    I know that the "addback" is an added function present in jquery 1.8 and later but I'm not sure how exactly how the 1.10 is used on the initial load of the page, but lost afterwards.  I believe that SharePoint defaults to jquery 1.7 something.

    Any help would be greatly appreciated.  I hvae a VERY tight deadline so a prompt response would be so helpful!!

    Hi Jacob,

    Telerik controls internally use jQuery 1.9.1. That's why you should add additional jQuery reference, especially if its version is different in order to avoid conflicts in jQuery versions. It would be better if you reference the embedded jQuery via the ScriptManager:
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
