Issue with Firefox 3.5 and firebug

If you’re using FF 3.5 to view any website and have firebug enabled,
you may encounter an annoying javascript error:
“onreadystatechange FAILS Error: Permission denied for XXXX to create
wrapper for object of class UnnamedClass Error”
This is a FF3.5/Firebug issue and is not a bug of the website
Unfortunately, there is no real good workaround if you need to have
firebug on except that disabling the Net tab may help reduce the
chances of getting the error. But if you don’t have to use firebug,
simply turn it off.
