It stays indefinitely on Chrome. There's a bug in Firefox which auto-closes it after 4 seconds: https://bugzilla.mozilla.org/show_bug.cgi?id=875114

Answer 2

Try with "requireInteraction" in the option, will work in firefox and chrome both. The code is:

var options = {
                  body: "due to your inactive response timer is stoped automatically. Start your timer again.",
                  dir : "ltr",
                  requireInteraction: true
              };
