There was a problem in our implementation of menubar.opml that didn't show up in Chrome, but did in Firefox. Thanks to James Petry for spotting the problem and suggesting the fix.

There was a problem in the new Outline settings dialog when displaying an outline with the font, size and/or line height not specified. We now check much more carefully for the presence of these value.

There was also a report of the description not "sticking" but I have not been able to reproduce it here.
