I’m doing the web app on Tizen. It allows users to login with Facebook and Twitter. 

Twitter is okay. But in case of Facebook, it is not working. 

Actually, after login Facebook on Tizen mobile browser, I tried to login with FB on our site within browser. I could login automatically via FB.

But, in case of my web app on Tizen, I could not login with FB even though I tried to do automatically (I’ve already logined on FB). 

In addition, Facebook’s contents are not aligned on my web app. 

How can I fix this? Please let me know.

Thanks.
