          <p>Hello! can you please try reproduce it with xperf traces in two ways</p>
          <ul>
          <li>with our product</li>
          <li>without product</li>
          </ul>
          <p>As developers can see - 2/3 of memory is taken by Firefox</p>

              <p>@harlan4096 hi, if you can do 3 scenarios - it will be great. Or you can check with active and pause protection </p>
