Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2b1pre) Gecko/20091011 Namoroka/3.6b1pre ID:20091011033822 The default full screen button which is displayed when the user hasn't moved it from the customize sheet to the toolbar doesn't obey the current toolbar settings and is always shown as a button. Steps: 1. Open customize toolbar sheet and click on reset to default 2. Switch to text only mode 3. Switch into fullscreen mode and check the fullscreen button on the right side 4. Leave fullscreen mode 5. Open customize toolbar sheet again and d&d the fullscreen button to the toolbar 6. Enter fullscreen mode As you can see the fullscreen button behaves differently between step 3 and step 6. It's something I have already discovered on bug but haven't got feedback so far - probably it was a bit unclear description.

It will require an update of the litmus test: https://litmus.mozilla.org/show_test.cgi?id=9534

The 'text' and 'icons and text' options were removed in Firefox 29.
