What is the best way to turn off Javascript while using Selenium with Java?

Currently, I am utilizing Selenium for web testing using Java programming language. My objective is to disable JavaScript on the Firefox Browser, Google Chrome Browser, and IE Browser.

I have attempted the following code specifically for the Firefox Browser.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("javascript.enabled", false);
WebDriver driver = new FirefoxDriver(profile);

Unfortunately, an error occurs on the second line as shown below:

Exception in thread "main" java.lang.IllegalArgumentException: Preference javascript.enabled may not be overridden: frozen value=true, requested value=false

If you have any insights on disabling JavaScript when working with Selenium on various browsers, your assistance would be highly appreciated!

Answer №1

To enhance your browsing experience on Firefox, consider installing the Noscript add-on. Simply perform a right-click on the Add to Firefox button and select Save link as to download the .xpi file. Afterwards, follow these steps to configure the Firefox profiler:

FirefoxProfile profile = new FirefoxProfile();
profile.AddExtension(@"PATH\TO\noScript.xpi");
IWebDriver driver = new FirefoxDriver(profile);

driver.Navigate().GoToUrl("http://localhost:8080/");
