Steamgifts Plus Alternative FIX

I've woken up today and I got that shitty google chrome blocked the extension since it wasn't from chrome store.
I have a fix for it that you can download right here:

Instructions:

1- Download and uncompress it.
2- Go to chrome Extensions tab.
3- Check the tickbox of developer mode.
4- Click on "Load uncompressed extension" button.
5- Navigate to the uncompresed content folder of my zip file and load it. It should work.

The fix is a simple json that I made and put in the same folder of the original js.

Here's the json file content for if you don't trust my files, so you can do it by yourself:

manifest.json CONTENT:

{
"manifest_version": 2,

"name": "Steamgifts Plus Alternative of Alternative",
"description": "Steamgifts Plus Alternative of Alternative given by Chikitown.",
"version": "1.0",
"content_scripts": [
{
"matches": ["http://www.steamgifts.com/*"],
"js": ["steamgifts-plus-alternative-install.user.js"]
}
]
}

I hope it helps and sorry if my english is not clear enough, I'm spanish like you can see in the screenshoots.
Cheers, Chikitown^^
