Firefox has been hiding a classic arcade game in plain sight, and here’s how to unlock it
Firefox has apparently been hiding a playable Snake game inside its address bar, and a Reddit user stumbled across it completely by accident while doing some quick math.
The discovery showed up on the Firefox subreddit just a few hours ago after a user said they were using Firefox’s built-in calculator shortcut and suddenly unlocked a game instead. The short video they shared shows them typing 25*6 into the address bar, which returns a result of 150. A small Firefox icon then appears next to the answer. Clicking that icon launches a retro Snake-style game inside a pop-up window.
I tried it myself after seeing the post, and the hidden game is real.
At first, it looked like 25*6 might be a special trigger. It isn’t. The actual requirement seems to be getting a result of exactly 150.
I tested several different calculations and all of them unlocked the same game:
1 × 150
2 × 75
3 × 50
5 × 30
6 × 25
10 × 15
Every one of those produced the Firefox icon and launched Snake.
The trigger is also a little more specific than the original post makes it seem. You can’t just click the calculator result itself. Firefox only opens the game if you click the tiny Firefox logo that appears beside the calculated answer in the address bar suggestions. Clicking elsewhere in the suggestion list doesn’t do anything.
My testing matched what several commenters reported in the Reddit thread. One user noted that the game works with any equation that equals 150, while another pointed out that you have to click the Firefox icon next to the answer for it to launch. A few people said they couldn’t get it working at all because that icon wasn’t showing up in their version of Firefox.
The game itself is about as simple as you’d expect. It looks like a stripped-down version of Snake with Firefox branding tucked into the interface. You can control the snake with your arrow keys. Someone in the thread mentioned they noticed a lot of input lag, but it worked just fine on my end on a M2 MacBook Air.
Mozilla hasn’t publicly documented the feature as far as I can tell, which explains why some long-time users in the thread also were clueless about the Easter Egg.
Firefox doesn’t explain why 150 is the magic value, and nobody in the thread seemed to know either. My best guess is that they might have introduced the game with Firefox v150, but everyone missed it. But again, this is just speculation, and I could be completely wrong.
If you want to try it yourself, open Firefox, type any multiplication that equals 150 into the address bar, wait for the calculator result to appear, and click the small Firefox icon beside the answer. That’s where the game is hiding.
