Question: When I try to test installing my app in the Firefox OS simulator and phone I get "Download stopped" error and the application does not get installed even though the application successfully passes the Firefox validator.

See package manifest.

```
{
    "name": "FriendFinder GPS",
    "package_path" : "http://wormholesoft.com/ffos/FriendFinder/FriendFinder.zip",
    "version": "1",
    "developer": {
        "name": "NAME",
        "url": "http://Wormholesoft.com/ffos/FriendFinder/FriendFinder"
    }
}

```

Answer: 
Without using JavaScript, the only way I could think of doing this off the top of my head is by explicitly setting the `height` property of `.item` to a certain amount of `px`, together with `height: 100%;` on `.portfolioItem`

EDIT:
As such: <http://jsfiddle.net/3HP5A/>
exactly how it is.

```
.portfolioItem {
    display: inline-block;
    position: relative;
    width:40%;
    height:100%;
}

```
