I have not noticed any recent updates happening to Aurora release though there might be add-on updates gone in recently.
I do not see any start in safe mode exe either.
I have tried running as an administrator but no user (it anyway does not look like an authority issue)
Please help.
Other details if needed:
Win 7 64-bit.
Intel Core2Duo 2.2

When I start Aurora it is showing XML Parsing error and without opening. The error message shown reads as below in full: ___________________________________________________________ XML Parsing Error: undefined entity Location: chrome://browser/content/browser.xul Line Number 540, column 9: <button default="true" -----------------------^ ___________________________________________________________ I have not noticed any recent updates happening to Aurora release though there might be add-on updates gone in recently.
