Amazon AWS S3 Error: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I am trying to upload files from my browser app to s3 but I get the following error when uploading:
No 'Access-Control-Allow-Origin' header is present on the requested resource.

Need to configure your CORS Settings for your bucket on amazon s3 console.
To edit your S3 bucket permissions:
  1. Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/
  2. In the Buckets list, open the bucket whose properties you want to view and click "add CORS configuration"
  3. Write the rules you are willing to add in between the tags <CORSConfiguration>

<CORSConfiguration> <CORSRule> <AllowedOrigin>http://www.yourdomain.com</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <AllowedMethod>POST</AllowedMethod> <AllowedHeader>*</AllowedHeader> </CORSRule> </CORSConfiguration>
