The release notes that appear from the Help menu are the M10 release notes (not the M13 or M14 release notes)
This happened with the M12 release (bug # 21992) -- looks like it needs to be fixed again. I can't make changes to the menu so I'm reassigning it to leaf. Any chance we can get this fixed permanently? P.S. I put a redirect in the M10 release notes, but I think when the notes get Mozilla-ized, the redirect breaks.
Now i just need to fix all.js on the branch...
I will verify this bug (based on what I see in lxr today)
