If you do not enable the tracking scripts on the page (google analytics) then the &quot;&#x2F;game&quot; entry point after signup just endlessly reloads itself automatically in Firefox 42.0. I can watch the page load resources in the developer console. There are a couple of different stopping points. One is when it loads all the way to &#x2F;api&#x2F;user-config while the tab has focus, then it starts reloading. Another case is where I leave the tab, then I load all the way to &#x2F;api&#x2F;tutorial&#x2F;?userBase=XXXXXX&amp;tutorial=true plus some images (ending with logo.png). As soon as the tab gains focus again, it triggers a reload.
