I upgraded firebug just today, and since then I'm getting the following 2 errors in extjs-all.js
Permission denied for <http://localhost:8089> to call method UnnamedClass.toString on <>.
uncaught exception: unknown (can't convert to string)
These two are exactly on the following line
in the implementation of swfobject
var aa = Y.appendChild(ab);
Although this error only appears while firebug window is opened, I'm still curious where that come from, especially that I don't have any swf/flash embeded objects
Best regards and thanks
