1) Search the word “Twitter” in your Facebook account and add the “Twitter” application that shows at the top side in the search results.
2) Now Allow Twitter to access your profile.
3) Log into your Twitter account (via the Twitter application inside Facebook).
Now your Facebook messages will also show up in Twitter! But there’s one more step to send information from Twitter back to Facebook…
4) After you test out the Facebook to Twitter functionality by typing a message and clicking on “Update,” click on “Allow Twitter to Update Your Facebook Status”
5) Allow status updates from Twitter back to Facebook.
6) Now check the twitter account from another browser by logging in your twitter account.
So guys Cheers!!!!
