User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0 Build ID: 20120726160848 Steps to reproduce: 1. Load this page: https://developer-new.mozilla.org/en-US/docs/HTML/HTML5$translate?tolocale=fy-NL 2. Scroll down until the top of the WYSIWYG has a tapered white border. 3. Press the fullscreen button. Notice problem. 4. Scroll up until the tapered border disappears. Notice problem is gone. Actual results: Page looks weird (https://bug766658.bugzilla.mozilla.org/attachment.cgi?id=637259). If you scroll up until the tapered border disappears and then hit the "fullscreen" button again, it works fine. Expected results: Normal fullscreen (the second half of "What happened" above).
Morphing this bug a bit. I can not reproduce what John described a year ago with the new design now. These issues seem to be gone. However, if you go to full screen mode when editing a translation, the wysiwyg tool bar is gone at all. So you can't save or get back to the normal view. Also hitting the Esc key as a shortcut to quit full screen mode would be nice to have in both, translation edit and normal page edit.
