The Click Me logo is part of the Humble Mozilla Bundle promotion - once clicked you should be able to control the character with the "WASD", and "IJKL" keys. Quoting '''the-edmeister''' from https://support.mozilla.org/en-US/questions/1025706 ----------------------- That Click Me game is part of the Humble Mozilla Bundle promotion on the default Home Page [about:home], that loads from the Mozilla servers in the "Brand Logo" (DIV) section of about:home. A feature that was first used in Firefox 29 [IIRC] just prior to the start of the Olympic Games. Also, part of that promotion is addressed in the "Snippet" below the Search Container on the about:home page. If you want to block the "Brand Logo" section (and the "snippet" below the Search container) from ever being seen again, you can install Stylish and this UserStyle. https://userstyles.org/styles/104673/about-home-hide-snippets-and-hide-brand-logo
