Hi,

I tried to open edge(chromium) browser following below page.  
[https://docs.katalon.com/katalon-studio/docs/open-chrome-with-extensions.html](https://docs.katalon.com/katalon-studio/docs/open-chrome-with-extensions.html)

Below image is my Katalon Settings.

However, it didn’t work.

I tried below code.

```auto
 System.setProperty("webdriver.edge.driver",msedgedriverPath);  
 EdgeOptions op=new EdgeOptions();
 op.addExtensions(new File(myExtensionPath));
 DesiredCapabilities capabilities = new DesiredCapabilities();
 capabilities.setCapability(EdgeOptions.CAPABILITY, op);
 op.merge(capabilities); 
 WebDriver browser = new EdgeDriver(op);

```

However, return below error.

It sounds like you’re not supplying a _List_ type to the `addExtensions` method.

The class documentation is here:

> **[EdgeOptions](https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/edge/EdgeOptions.html)**
>
> declaration: package: org.openqa.selenium.edge, class: EdgeOptions
