title: Selenium Grid, running multiple browser instances in parallel
body: <p>I'm using Selenium grid to run multiple instances of my test in parallel. I want to test if I can run a lot of browsers at the same time. My problem is that I can't have more that 5 five browsers at the same time, and I don't know why.</p>
  
  <p>Here are the commands I'm using to start the hub and the node:</p>
  
  <pre><code>java -jar %seleniumPath% -port 4444 -role hub -nodeTimeout 1000
  
  java -jar %seleniumPath% -role node -hub http://localhost:4444/grid/register -browser browserName=firefox,maxInstances=1,maxSession=1 -port 5555
  </code></pre>
  
  <p>NOTE: The two commands are working but what I don't understand are the <code>maxInstances</code> and the <code>maxSession</code> arguments. I set them to 1 but I can still run more than one browser and if I set them to 10 or more only 5 browsers will run at the same time.</p>
  
  <p>What should I do to have more than 5 browsers running at the same time?</p>
