When active, plugin puts stars in any input fields you type, hidding your typing. When inactive, it reveals all the 'hidden' fields.
It is highly recommended to disable autofill option before using this plugin for best performance. - If input box appears on page after clicking on something, restart your plugin (click off/on) before using it. This is because lots of pages uses hidden inputs, and this plugin is ignoring them in order to ensure the functionality of the page.
