NationStates++ (often shortened to 'NS++') is a tiny, light-weight, and open-source browser extension for NationStates. Focused on an easy-user experience, it is designed to simplify the NationStates game, provide players with more data and information to make educated decisions, and provide more powerful tools to interact with other players.
Browser extensions are tiny programs or apps designed to "extend" and add onto the existing features of your internet browser. All modern browsers support browser extensions, including Safari, Chrome, Firefox, and Opera.
Internet Explorer is not an open web browser and frequently does not support official web standards. In addition, it does not support browser extensions, and it frequently a target for malware and viruses. I suggest all Internet Explorer users upgrade to a free, modern browser, listed above.
The Nation Puppet Switcher only stores nations & password information locally in your browser local storage. This information is never transmitted anywhere, and never leaves your computer. In addition, I do not collect or monitor sensitive personal information or other identifying information.
Your browser likely does not have automatic extension updates enabled (this is a common problem with Safari). For Safari users, go to your preferences -> Extensions tab, and be sure to "enable" automatic updates. For Firefox users, go to Firefox -> Addons and click the settings gear in the upper right to ensure automatic updates are enabled.
