FAQ

What is the Prevent Duplicate Windows/Tabs plugin?
It detects when a user opens more than one browser tab or window for your site in the same browser on the same device.

What happens when a duplicate tab is detected?
The plugin triggers a “Duplicate tab detected” event, letting your workflow show a popup, alert, or block access to content.

Can it automatically close the duplicate tab/window?
Yes. You can enable an option to auto-close the duplicate tab/window, and you can set a delay (in milliseconds) before it closes.

How do I enable the detection on a page?
Place the Duplicate Windows/Tabs element on any page where you want the behavior to apply. It will monitor for duplicates when active.

What should I do in the workflow when the event fires?
Use the “A duplicate tab has been detected” event in your workflow to define what happens - e.g., show a modal, redirect, disable content, or whatever fits your app logic.

Does the plugin prevent all duplication always?
No. It detects and helps manage duplicate tabs/windows, but behavior may vary depending on browser caching or device specifics. Use it as a control mechanism, not as strict enforcement.

Who do I contact for support or to report bugs?
You can email the plugin support team with questions, suggestions, or bug reports (support contact is listed in the plugin’s documentation).
