Embedded widget --- menu links open on a different window | CMS 4.1.0 - XfW V4 R410

DiogoPuga · May 13, 2026, 3:18pm

Hi,

I’m Diogo from Portugal and I use Xibo quite extensively. My server is currently running version 4.1.0.

I’m facing an issue for which I haven’t found a proper solution yet.

I have a layout with some videos and a website embedded in part of the screen. The problem is that the website was poorly developed and some menu links open in a new window/tab. Even in Chrome or Edge outside of Xibo, those links open a new tab.

I managed to solve the issue in normal Edge by using browser extensions that block popups/new tabs. However, when I try to use the same extensions with Xibo’s embedded Edge browser (EBWebView), they do not work.

Is there any way to prevent Xibo from opening new windows/tabs from an embedded website, or to force all links to stay inside the same embedded window?

Any help would be appreciated. Thanks!

Hi DiogoPuga,

Thank you for reaching out to Xibo Community!

You may try to use an iframe in your HTML section in the ‘Embedded’ widget as shown on the image below. I have tested it to be working with the Xibo cloud CMS V4.1.0 and Xibo for Windows (XfW) V4 R406 player on a Windows 11 machine. What the iframe does is encapsulate your website in the player app, and when you click on any link on the webpage, it shows the page inside the player app. You can download the test layout I have created for you here. Please schedule it on your display to test.

<iframe
  src = "https://www.manilatimes.net/" 

  width = "1920" 

  height = "1080" 

  style = "border:none;">
</iframe>

In this example, I have a publicly available website (no login password required to access the website content) that I wrapped in an iframe.

Also, please enable the mouse in the CMS display page. To do so, click on the display entry, click on ‘Edit’, go to the ‘Settings’ tab, and scroll down to find the ‘Enable Mouse’ option by ticking it and finally ‘Save’ it. You will need to restart your XfW player for the changes to apply.

Kind regards,

Jerry

Hi Jerry,

Thanks for the ultra-fast reply.

I tried it both on my own layout and by scheduling your test layout, but my monitor stays black.

In the logs I can see this error:

2026-05-14 15:35:52 WebCefWebView_LoadError: Cannot navigate. e = ERR_BLOCKED_BY_RESPONSE, code = BlockedByResponse

Is there anything else that I need to configure or enable for this to work?

Thanks again for your help.

Hi DiogoPuga,

Sorry to hear about the issue. Could you please confirm that you are using the latest Xibo for Windows (XfW) player V4 R406? If not, could you please download it here and then test it to see if you are still getting the same error?

Also, are you able to open the website when you directly access it on a Google Chrome browser?

Hope to hear from you soon!

Kind regards,

Jerry

Hi DiogoPuga,

Thank you for your response!

The error you are getting seems to be a header configuration on the website that does not allow encapsulating the webpage in an iframe, thus the error. The configuration is particularly the “X-Frame-Options: SAMEORIGIN”. I just wondered since the website in the test layout I sent you does not have that header configuration; hence, it worked on my end, and I’m wondering why it’s not working on your end.

When I checked the publicly available website I used for testing, which is https://www.manilatimes.net/, and checked it in the website security header checker https://securityheaders.com/. As you can see, it does not have the X-Frame-Options in the website header

I have sent you a DM. Could you please respond to the DM with a copy of your layout for me to check and test on my end?

Kind regards,
Jerry

Hi Jerry,

I’ve already sent you the DM, and I also managed to find a solution for the multi-window issue.

I found a Xibo Player project on GitHub and edited the CefSharpLifespanHandler by adding a new line inside the OnBeforePopup function:

chromiumWebBrowser.Load(targetUrl);

With this small fix, I’m now able to use my website without opening new windows.

Best regards,

Hi DiogoPuga,

I have tested your layout, and it is working on my end without the need to make any changes on the player. I have the same XfW V4 R406 with test cloud CMS V4.1.0. I am unable to replicate the issue on my end as links on your website open inside the webpage widget.

I’m posting your solution here to help other users that might be having the same issue.

On another topic

I found a Xibo Player project on GitHub and edited the CefSharpLifespanHandler by adding a new line inside the OnBeforePopup function:

chromiumWebBrowser.Load(targetUrl);
protected override bool OnBeforePopup(
    IWebBrowser chromiumWebBrowser,
    IBrowser browser,
    IFrame frame,
    string targetUrl,
    string targetFrameName,
    WindowOpenDisposition targetDisposition,
    bool userGesture,
    IPopupFeatures popupFeatures,
    IWindowInfo windowInfo,
    IBrowserSettings browserSettings,
    ref bool noJavascriptAccess,
    out IWebBrowser newBrowser)
{
    newBrowser = null;

    chromiumWebBrowser.Load(targetUrl);

    return true;
}
With this small fix, I’m now able to use my website without opening new windows.

Kind regards,

Jerry
