Something to be aware of before you go Pong-ing is that you will have to make some (temporary) changes to your Firefox toolbar settings,
Web browsers seem to enjoy hiding fully playable games inside of themselves, from text-based adventures to one of human history’s earliest examples of a video game (i.e. Pong). And wouldn’t you know it, Mozilla Firefox just so happens to be hiding its own version of digital table tennis down in its proverbial guts.
This isn’t a new addition, either — the game has been tucked away in Firefox’s code for several years inside its Customize Toolbar options.
