New Plugin - Prevent Duplicate Windows/Tabs

Hey everyone,
we have just released the " Prevent Duplicate Windows/Tabs" plugin.
This plugin allows you detect if a user has opened more than one window/tab within your website at the same time. Once a new tab/window is detected, an event is triggered. You can show a popup, alert or block access to your page’s content.You can also choose whether or not the window/tab should automatically close and set the delay.

For a demo of this plugin please visit:

Have a great day!
Noel from Anticode
