Using the attached test page
1) Start recording in FF
2) Using DOM Explorer to locate the only <span> element
3) Add a Verify InnerMarkup Exact verification step
4) Run the test in FF

Expected: The test to pass
Actual: The verification fails saying:
Content.InnerMarkup of 'WhatWouldSpan' does not match!

   Match Type: 'Exact'
   Expected Result: '&nbsp;What would you
                            like to do?&nbsp;'
   Value at time of failure: 'What would you
                            like to do?'

Note: The same steps work as expected in all other browsers. Only FF has this problem.
