If you’re a fan of the classic Pong game, then you’ll love Mozilla Firefox’s hidden unicorn game. This game is easy to play and can be enjoyed on any device. To start, open Mozilla Firefox and sign in with your Mozilla account. Then, click on the three lines in the top left corner of the main window. The first line will show you a list of all your current tabs. The second line will show you a list of all your open windows. The third line will show you a list of all your active tabs and windows. If there are any tabs or windows that are not listed, then they are not currently active and will not be shown in this list. If there are any tabs or windows that are not listed but they have been added to the list as recently as the last time you checked it, then they have been added to the list as recently as the last time you checked for new tab arrivals (if they have). If there are notabs or windows that are not listed but they have been added to the list as recently as the last time you checked for new tab arrivals, then they have been added tothe list as recently as the last time you checked for new tab arrivals (if they have). To play hidden unicorn pong, simply click on one of these three lines in order to bring up a new window with information about how to play: -The first line shows how many players there are online: if there is only one player online then it says “No players online.” If there are more than one player online then it says “There is at least one player online.” -The second line shows how many buttons there are: if there is only one button then it says “There is only one button.” If there are more than one button then it says “There may be more than one button.” -The third line shows how many paddles there are: if there is only one paddle


It seems like every browser has a hidden game these days. Chrome has a dinosaur game, Edge has surfing, and Firefox has . . . unicorn pong? Yep, you read that right—here’s how to play it.

First, open Firefox. Click the hamburger menu (the three horizontal lines) at the upper right, and then click “Customize.”

On the “Customize Firefox” tab, you’ll see a list of interface elements to configure the toolbar.

Click and drag all the toolbar items except “Flexible Space” into the “Overflow Menu” on the right.

Click the Unicorn button that appears at the bottom of the window.

A Pong-like game with a small unicorn icon will appear on the left side of the tab. In this version of the game, the “Flexible Space” box serves as the Pong paddle, and the unicorn icon is the ball.

To play, just use the arrow keys on your keyboard to position your paddle so the unicorn doesn’t move past it. As Atari Pong’s famous instructions said, “Avoid missing unicorn for high score” (or something like that).

If you lose and want to play again, just double-click the Unicorn button.

When you’re done playing, click “Restore Defaults” to quickly remove all the items from the “Overflow Menu.” Click “Done” to close the “Customize Firefox” tab.

Now you can tell all your friends you’ve played Unicorn Pong. If they don’t believe you, just send them the link to this article.
