Doesn't work for me.<p>If I leave it a while, I eventually get a notification pop-down saying "This page is slowing down Firefox. To speed up your browser, stop this page."<p>Is it Chrome only?<p>Whatever it is, it sounds like someone's implemented a very simple feature very badly - a bouncing logo is the type of thing people made in basic "DHTML" on the old web, not something that should be slowing down a browser in 2022...
