Firefox OS Manifest .htaccess Handler
Want to know one of the secrets why Firefox OS is so incredibly awesome? If you've created your website correctly, i.e. using CSS media queries (responsive design) and JavaScript feature detection, you can simply add an app.manifest file at the root of your domain and you've instantly created a Firefox OS app! Of course you'll then want to list your app in the Firefox Marketplace. The most frequent problem developers run into is with their app.manifest file not being served correctly. With an update to the .htaccess file of the hosted app, that problem can go away!

The problem is that the manifest.webapp file isn't being served properly, so an AddType is the key:
AddType application/x-web-app-manifest+json .webapp
The .htaccess snippet above ensures that the manifest is served correctly, thus eliminating the annoying manifest error and letting you get your app listed on the Marketplace!

Yeah, I'm a Photoshop wizard. I rock the selection tool. I crop like a farmer. I dominate the bucket tool. Hell, I even went as far as wielding the wizard wand selection tool once.
...OK I'm rubbish when it comes to Photoshop.
In my nginx config manifest listed as(taken from mime.types file):
