Write this in Your Code

 webBrowser1.ScriptErrorsSuppressed = true;

To disable the script error pop up, you need to go to (in Internet Explorer) Tools->Internet Options, there go to the Advanced tab, and in Browsing select Disable Script Debugging (Other), but, the problem may be related to the fact that every site loaded in the WebBrowser control is rendered in IE7 patibility mode, to solve this the only thing you can do is a registry hack like this: WebBrowser control to use IE9

change your registry to 2af8 which is IE 11 for devenv.exe software/Microsoft/internet explorer/main/featurecontrol/feature_Browser_emulation

If your working with a GUI (like in Visual Studio) just go to the Webbrowser Properties and set "ScriptErrorsSuppressed" = true

It is easy to see how this error has been eliminated. But Visual Studio uses Internet Explorer and another Web Browser coding is hard. If you look at the versions, the last Visual Studio one uses IE 11 for WebBrowser tool.

The C++ GUI is remended for one of each encoding: https://msdn.microsoft./en-us/library/60k1461a.aspx
