Overview
The NST WUI supports the latest Google Chrome, Mozilla Firefox and Apple Safari web browsers as well as the Microsoft Windows Internet Explorer (IE) (Version: 11 or greater) and Edge web browsers. Special consideration and endless testing for supporting these browsers has been maintained by the authors.
For browser support with a mobile touch device see the page: HowTo Use a Touch Device (iPad) with NST.
The Google Chrome browser renders pages most quickly due to the performance increases made to its JavaScript engine.
The NST WUI is JavaScript intensive and makes heavy use of "Tab Browsing" to support a wide variety of rendered visual results and enhanced navigational flow. This section will describe various browser optional settings, plugins and add-ons that are required or can be used to improve the experience and/or development with the NST WUI.
Fixed Font Browser Setting
Use the following fixed font families for the fixed width setting in your browser for best results when viewing the NST WUI Console output. The fixed font family to use for each Operating System is shown and is browser independent:
| Mac OS X | Linux | Chrome OS | Windows |
|---|---|---|---|
| Menlo | Monospace | DejaVu Sans Mono | Consolas |

IE
Certificate Error
When connecting to a NST probe, IE will display a page similar to that shown below:
This expected message is shown because an encrypted https connection is used when communicating with the NST probe. One should select the "Continue to this website (not recommended)" link to continue to the NST WUI.
Settings

Developer
Enable JScript Debugging For IE
The following can be done to enable "JScript" debugging - Microsoft's ECMAScript implementation. This is analogous to the Mozilla Firefox JavaScript implementation.
First enable "script" debugging on the Microsoft Windows Internet Explorer (IE) browser. This is found within the "Advanced" tab on the "Internet Options" window. Un-check the box next to: "Disable script debugging (Internet Explorer)".
Next download the Microsoft Script Debugger for Windows. This tool is relatively small in size can be quite useful for debugging "JScript" client side code.
Finally the Microsoft Windows Internet Explorer (IE) web browser will need to be restarted. A new menu item for script debugging will appear under the "View" menu. If a "JScript" error occurs the debugger will be automatically invoked. One can also set "breakpoints" to invoke the debugger at a specific location within the "JScript" code.
Add A Developer Toolbar For IE
The Microsoft Windows Internet Explorer (IE) Developer Toolbar provides a variety of tools for quickly creating, understanding, and troubleshooting Web pages.
