You can set the useAutomationExtension
capability to false.
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(options);
This capability will help to not load Chrome Automation extension. Due to which, “Failed to load extension” popup would not appear.
But please note you will not be able to perform any window resizing/positioning operations without the Chrome automation extension.
Hope this helps!
