FireNes, a way to play NES games in your Firefox
Today’s my birthday and I’m feeling kind of nostalgic. I miss the old NES games I use to play when I was a kid, Contra, Super Mario Series, and Gradius to name a few.
Then I stumble upon FireNes. This is an add-on for the Firefox browser that allows you to play 2,000+ NES games. You can download the FireNes installer from its site. Once installed, you can access FireNes from Firefox by going to Tools>FireNes.
It will open a sidebar with the games listed alphabetically. Choose a game by double clicking and a popup window will open. Controls are simple. All you need to press are the arrow keys for direction, Enter for start, Ctrl for select, Z for B and X for A.
Every game made for the NES is available. You most likely will find the game you wasted your time on in the past. I give the FireNes add-on two 1-up mushrooms.![]()
