Solution 1

I don't know Java, but maybe a solution for Python 3 will help you.

in Python, you can use Options() instead of FirefoxProfile() to deactivate JavaScript:

from selenium.webdriver.firefox.options import Options
options = Options()
options.preferences.update({"javascript.enabled": False})
driver = webdriver.Firefox(options=options)
driver.get('about:config')

Maybe Java this:

FirefoxOptions options = new FirefoxOptions();
options.preferences.update({"javascript.enabled": False});
WebDriver driver = new FirefoxDriver(options);
driver.get('about:config')

Solution 2

You change the preference value using profile with lots of options:

DesiredCapabilities capabilities = new DesiredCapabilities();
// setCapability(SUPPORTS_JAVASCRIPT, javascriptEnabled);
capabilities.setJavascriptEnabled(false);

FirefoxBinary binary = new FirefoxBinary( new File( binaryPath ) );
FirefoxProfile profile = new FirefoxProfile();

//profile.setPreference("preferenceName", "Value");
profile.setPreference("javascript.enabled", false);

RemoteWebDriver driver = new FirefoxDriver(binary, profile, capabilities);

To view the preferences, you can visit the URL about:config

Solution 3

As per Selenium 3.6 Java Client Release, the easiest way to disable Javascript in the browser would be to set the setJavascriptEnabled argument through DesiredCapabilities to False and merge it with FirefoxOptions as follows:

package demo;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.DesiredCapabilities;

public class Q46883024_setJavascriptEnabled 
{
    public static void main(String[] args) 
    {
        System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
        DesiredCapabilities dc = new DesiredCapabilities();
        dc.setJavascriptEnabled(false);
        FirefoxOptions op = new FirefoxOptions();
        op.merge(dc);
        WebDriver driver = new FirefoxDriver(op);
        driver.get("https://google.com");
        driver.quit();
    }
}

While execution, the browser you are using may override the setJavascriptEnabled settings.

In my feature automation, I need to disable JavaScript in browser and run the flow. How to disable JavaScript?

Tried DesiredCapabilities for firefox and Chrome.
```
DesiredCapabilities dc = new DesiredCapabilities();
dc.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, false)
```
And
```
DesiredCapabilities dc = new DesiredCapabilities();
dc.setJavascriptEnabled(false);
```
For firefox, tried 1) Setting up profile for firefox

2) Adding add-on - noScript.xpi

3) profile.setPreference("javascript.enabled", false);

4) Through UI, tried changing the flag - "javascript.enabled" in "about:config" to false. Here, opened firefox and gave "about:config" getting a warning - "This might void your warranty!". There is a button - "I'll be careful, I promise!" with id - warningButton. This button should be clicked to proceed further. To click this button, used driver.findElement(By.id("warningButton")).click(); but it not work.

All the above options are not working. Any advice will be helpful.

This code works now for firefox,public void testDisableJS() throws Exception { WebElement element; driver.get("about:config"); driver.findElement(By.id("warningButton")).sendKeys(Keys.E‌NTER); element = driver.findElement(By.id("warningButton")); Actions act = new Actions(driver); act.moveToElement(element).click().perform(); act.sendKeys(Keys.RETURN).sendKeys("javascript.enabled").p‌erform(); Thread.sleep(1000); act.sendKeys(Keys.TAB).sendKeys(Keys.RETURN).perform(); Thread.sleep(1000); driver.get("google.com"); }

the selenium version which i use is not supporting FirefoxOptions(), guessing it should be upgraded. So unable to try this option. Also not want to upgrade now. Will definitely try this option after upgrade.

Yeap, that's why my Answer stats with Selenium 3.6 Java Client Release but you haven't mentioned your Selenium version.

Question: "javascript": 2 .... what does the number 2 means? Disable? And what would 0, 1, 3 ,4,.... mean?
