mahdisml If you use the Clay.io plugin, and publish your game to the Clay.io Marketplace. You can then push your game to the Mozilla Marketplace by following there guide.
I have a fully reviewed, and approved game on the Mozilla Marketplace. Mozilla's review process took about a week, and they are a little more strict than others like Facebook, and Chrome. I got two denial letters before it was finally approved. But they let you know exactly what you need to change, and or fix to resubmit. This just insures a higher quality, bug free game.
