Google+Facebook allows you to see your Facebook stream inside Google+. Simply Connect to Facebook, and get all the updates on your Google+ Facebook tab. This will add a new Facebook tab before the home tab in Google+.
Here is a preview screenshot of Google+Facebook:
Extension, called ’Google+ Facebook’, lets you add the Facebook stream to your Google+ homepage. Once installed, it displays a Facebook icon in the top menu bar, left to the Google+ home icon. The First time, when you click on the Facebook icon, you’ll be asked to connect your Facebook account.
When you’re done with connecting, your Facebook wall stream will appear inside the Google+. You can scroll down to see all the Facebook updates. Also, if you want to update your Facebook status right from the Google+ homepage, just click on the ‘What’s on your Mind’, it will open up a pop-up window where you can type in your status update.
