Is there any capabilities to set Firefox browser zoom level to some specific percent throughout script execution?

Question

I'm using Firefox browser and i want to set the zoom level 90% while it executing the script.

I have tried to set using JavascriptExecutor like -

((JavascriptExecutor)driver).executeScript("document.body.style.transform='scale(0.9)'");

Its working for specific command lets say in my Listeners file i have place this if its a get command. it resize the browser after get URL and then it restored back to default once another command getting executed.

I'm looking for the solution like DesiredCapabilities of things so there i can add the zoom level for the browser.

How about setting the size of the window once you figure out what size suits your requirement? — eduPeeth, Jul 05 '18 at 08:29
You can't set zoom. But you can set `layout.css.devPixelsPerPx` to `0.9` to simulate a zoom level, that is in the firefox profile — Tarun Lalwani, Jul 05 '18 at 08:31
@TarunLalwani, can you brief me how do i use this one in my code ? — NarendraR, Jul 05 '18 at 08:33
You could use robot class to simulate the keyboard event - Control & Subtract - to zoom out of the browser — Sijin, Jul 05 '18 at 10:55

FirefoxProfile profile= new FirefoxProfile();
profile.setPreference( "layout.css.devPixelsPerPx", "0.9" );
WebDriver driver = new FirefoxDriver(profile);

The above will set the firefox profile preference and simulate a zoom level of 90% for 110% set it to 1.1

How about something like this one -

import org.openqa.selenium.Dimension;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class A {

    public static void main(String[] args) {
        WebDriver driver = new ChromeDriver();
        driver.get("http://www.google.com");
        driver.manage().window().maximize();
        Dimension dMax = driver.manage().window().getSize();
        int mHeight = (int) (dMax.height *.9);
        int mWidth = (int)(dMax.width *.9);
        Dimension d = new Dimension(mWidth, mHeight);
        driver.manage().window().setSize(d);
        System.out.println( driver.manage().window().getSize());

    }

}

This sets the window size 90% not the content of a site to be visible in zoom level 90 — NarendraR, Jul 05 '18 at 08:38

There is not the capability level option is available in Firefox. But screen size can be increased or decrease by webdriver:

driver.manage().window().setSize(value);
