Make the Ugly Scrollbars on your Facebook App Disappear
If you have annoying scrollbars around your Facebook app’s canvas, here’s what you need to do:
First, go to your app’s settings, click “Edit App” and then “Advanced” on the right.
Scroll all the way down to “Canvas Settings” and change “Canvas Height” to “Settable”.
That’s it! Gorgeous app, no scrollbars!
