You no longer have to type HTML source code to edit your custom Facebook page tabs. We’ve added a WYSIWYG editor as an option when you’re setting up your page tab using our Static IFRAME Tab app. You can easily switch between Source and Editor mode depending on your preference. You can also use the new Open in new window option at the top to give yourself plenty of room for your HTML editing. If you haven’t tried it yet you can install a page tab here.
