i m using windows 8 release preview but as told my friend have window 7 home basic ,
coming to browser tried all with opening facebook opened in one of tab of every browser

chrome : sometime do works n sometimes dont ,in case when i m not logged in n try to vote some one by clicking on vote n then following log in with facebook, it works but when i use top right cornered log in with fb it got me this error

Firefox mozila : when i click on log in with facebook on following vote without login ,there appear a small box of sync the account like where i allowed on first time.
and then disappear n page refresh without login n take to contest home page (contest info page)

internet explorer :
in this case everything happens as mozilla but page do not refresh

i know i have release preview but it (fb login button works for other website )
i hope i m not incorrect anywhere
