Well, they did it with Mario – so why doesn’t the Legend of Zelda deserve a Firefox theme?  MoZelda (get it? Mozilla = MoZelda) is an awesome looking Firefox 3.5 theme that will be helping you battle Moblins before you know it.
With what looks to be some original art, mixed with some Link shots from the latest Zelda game, this theme is very visually appealing and colorful.  Also, it scores points with me because it is Zelda, probably one of [...]

I can not get enough of the Mushroom Kingdom theme for Firefox.  In version two, a lot of the icon work has been re-done to make it even more colorful and unique.  As the author of the theme said, “All of the icons are new, but kept close to the originals to remain familiar to previous users.”  Personally, I like the changes.
This is a very worthy tribute to Nintendo for sure.  Go check out my thoughts on the previous [...]

Ready to make your Firefox browser a little more Wii-like?  WiiFox, a new theme for Firefox, is based on the highly popular video game system the Nintendo Wii.  It doesn’t really rip anything off directly, it just takes inspiration really from the Wii’s own internet browser and interface. 
If you like the theme, be sure to let the developer know.  Since it is right now an “experimental” theme, I am sure feedback would be appreciated in any way you can [...]

Looks like somebody else has tried to put up a fresh new theme inspired by the local population of the Mushroom Kingdom.  You have Mario, Luigi and the rest of the gang here.  I have to say this is a beautiful piece of work.  Makes me so happy I could go bust brick with my head until I find a surprise. 
There is a lot to love about this new Mario theme for Firefox.  For example:

This is not [...]

A somewhat questionable Firefox addition, FireNes promises to deliver you more than 2,500 Nintendo games in your browser.  After doing some research, it appears this addon is fetching games from another online Java powered NES emulator.  Controls are limited to arrow keys, Enter, Ctrl, Z and X – but hey what do you expect?
They are just Nintendo games after all.
You can pickup the add-on via Mozilla’s web site (after registration) or via Softonic.  If your looking for the same thing [...]

Seems like no matter where I turn, Firefox follows me everywhere! Thumbing through the instruction book for Super Smash Bros. Brawl – I noticed one of Fox’s names (from Star Fox) for his signature moves was a little familiar.
His “up” special move is called Fire Fox. Now the fan boy inside of me would like to think this is a nod to the fine folks at Mozilla from Nintendo but it is probably not the case.
Tell me [...]

So did the Super Mario Bros 3 theme not get you going yet?
Well if that one did not tickle your fancy, I bet this one will. It seems like now that somebody has developed a Mega Man 2 theme for Firefox. Yes, you too can bring the blue bomber in all his glory to your desktop.
Now what I want to know is where is the Metroid theme? How about some Final Fantasy or Castlevania?

Alright this is the most awesome thing I have seen all week! You know you love Mario, you couldn’t love that little chubby plummer? Now you can have him running around your installation of Firefox. Yes, this theme is totally dedicated to Super Mario Bros 3!
