+When you navigate to 3D Secure (3DS) authentication pages such as Visa or Mastercard, Selenium on Chrome or Edge may freeze or time out during execution. 
+
+**Why This Happens**
+
+3DS authentication screens load a third-party iframe that runs continuous background scripts from the payment gateway.
+
+Inside these iframes:
+   - Long-running JavaScript and postMessage listeners are always active.
+   - Messages are continuously exchanged with the payment provider.
+   - The browser keeps processing events and never reaches a fully loaded state.
+
+As a result:
+   - ChromeDriver waits indefinitely for the page to finish loading
+   - The pageLoad event never completes
+   - Selenium becomes unresponsive after navigation
+
+To prevent Selenium from waiting indefinitely, you need to add a desired capability to your test case that stops ChromeDriver from waiting for the full page load.
+
+This article discusses how to add the desired capability to the test case. 
+

+
+## **Steps to Add the Desired Capability to the Test Case**
+
+1. From the left navigation bar, go to **Create Tests > Test Cases**.
+   ![Test Cases](https://s3.amazonaws.com/static-docs.testsigma.com/new_images/projects/faq/selenium_faq_1.png)
+
+2. In the Test Case Explorer section, expand a **Feature** and a **Scenario** and select the required test case.
+   ![Test Case](https://s3.amazonaws.com/static-docs.testsigma.com/new_images/projects/faq/selenium_faq_2.png) 
+
+3. In the Test Case Details page, click **Run**.
+   ![Run](https://s3.amazonaws.com/static-docs.testsigma.com/new_images/projects/faq/selenium_faq_3.png)
+
+4. In the **Ad-Hoc Run** overlay, expand the **Desired Capabilities** section, enter the following:
+
+     | **Key** | **Data Type** | **Value** |
+     | ------------- | ------------- | ------------- |
+     | pageLoadStrategy | String | none |
+
+     ![Desired Capability](https://s3.amazonaws.com/static-docs.testsigma.com/new_images/projects/faq/selenium_faq_4.png)
+
+5. Click **Run Now**.
