My draft webpage currently has a <head> but no <body>. It links to a css stylesheet that exists in the expected location but is currently blank. When I loaded it into Firefox 17.0.1 for Win XP, the error console returned these three messages:
Could not read chrome manifest 'file:///C:/Program%20Files/Mozilla%20Firefox/extensions/%7B972ce4c6-7e08-4474-a285-3208198ce6fd%7D/chrome.manifest'.

Can someone help me interpret the messages so I understand what they mean?
