[🚀 Feature]: Node.js version with firefox missing full page screenshot option

[mrm-ot]

Feature and motivation

I have tried python version with firefox driver, it has a extra method for firefox driver.save_full_page_screenshot(screenshot_path).
Samething is missing for Node.js version.

We can use const image = await body.takeScreenshot(true) to take screenshot of whole page but it not same as save_full_page_screenshot. body.takeScreenshot it will scroll to the bottom when taking screenshot and if you have fixed header, header will be at the end of the page. driver.takeScreenshot does not take screenshot of whole page.

I assume it is a firefox only feature and uses built-in firefox screenshot tool. It works well with floating button and fixed header.

Usage example

await firefoxDriver.saveFullPageScreenshot(screenshot_path);

I have added example code with screenshot at the end

python

import time
import selenium.webdriver


options = selenium.webdriver.FirefoxOptions()
options.add_argument('--headless')


with selenium.webdriver.Firefox(options=options) as driver:
    page_url = 'https://chenzhihao.github.io/sticky-Nav/'
    driver.get(page_url)
    time.sleep(1)
    screenshot_path = 'screenshot.png'
    driver.save_full_page_screenshot(screenshot_path)

Node.js

import fs from 'fs';
import { Builder, By } from 'selenium-webdriver';


const driver = await new Builder().forBrowser("firefox").build();

await driver.get('https://chenzhihao.github.io/sticky-Nav/');

const body = driver.findElement(By.css('body'));

await new Promise(resolve => setTimeout(resolve, 1000));

const image = await body.takeScreenshot(true)
fs.writeFile('screenshot2.png', image, 'base64', console.log);

const image3 = await driver.takeScreenshot()
fs.writeFile('screenshot3.png', image3, 'base64', console.log);

await driver.quit();

Python Screenshot

Node.js Screenshot with body (navbar header is at bottom)
