Adjust Window for Firefox driver

[nrshoukhin]

How can I adjust window and take screenshot using Firefox driver?

[carranzpibisi]

It works for me:

$client = Client::createFirefoxClient('/usr/local/bin/geckodriver');

$width=1920;
$height=1080;
$size = new WebDriverDimension($width, $height);
$client->manage()->window()->maximize()->setSize($size);

$screenshot = $client->takeScreenshot();
$base64_screenshot = base64_encode($screenshot);
