title: Multi browsers vs multi tabs in Puppeteer
body: <p>I have 100 web pages that I have to test for runtime errors. I found the Puppeteer plugin that can do that "no sweat", but I ran into one dilemma: have one launched browser with multiple tabs or new browser for each link. What is the best approach in this case? </p>
  
  <p>In case of multiple tabs, I heard, there is a chance that css animation and something else (can't remember now) would not work when tab is not in focus.</p>
  
  <p>Multiple browser, obviously, causes the higher CPU load (no?)</p>
