How to Play Hidden Games on Firefox

This guide explains how to play Hidden Games on Firefox, with clear steps, practical tips, and important checks before you begin.

Next, choose "Customize Firefox" , and when you're done, you'll see a list of interface elements displayed on the right half of the screen.

Drag and drop interface elements from the right panel of the screen to the Overflow Menu box on the left. Pull out everything except "Flexible Space" .

When only "Flexible Space" is left, a new unicorn-shaped button will appear in the taskbar below.

Click on that button the Firefox unicorn game will launch. In the game, "Flexible Space" will act as a beam while unicorns act as a ball. You control the beam above to support the unicorn so that it does not shoot out of the screen and bounce back to the opponent. Your opponent is a bot, controlling the bottom beam.

To control, you just need to use the arrow buttons on the keyboard.

If you lose and want to play again, just double-click on the unicorn button. When the game is bored, click the "Restore Defaults" button to quickly return the interface elements to their original position. Click "Done" to close the "Customize Firefox" tab.
