Embedding a Twitter timeline
Create an embed code on Twitter, then add it to a Firefly page.
Creating the embed code on Twitter
Go to http://www.twitter.com, choose Log In and enter your credentials.
Select your profile photo in the top-right, then choose Settings from the drop-down.
You can customise the widget to change the timeline source or display options if you'd like, but the default settings work just fine for most purposes.
If you want to embed a timeline other than your own, simply change the username. The preview on the right will update accordingly.
Once the new widget has been created, the embed code is displayed beneath the preview. Copy it the usual way.
