Ns Error Factory Exists

[wellington1993]

I've got this error after Firefox Nightly Browser update:

JavaScript error: chrome://aboutsync/content/AboutSyncRedirector.js, line 43: NS_ERROR_FACTORY_EXISTS: Component returned failure code: 0xc1f30100 (NS_ERROR_FACTORY_EXISTS) [nsIComponentRegistrar.registerFactory]

and
JavaScript error: resource://gre/modules/WebNavigationContent.js, line 215: NS_NOINTERFACE: Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]

Repeated many times.

Thanks!

And this:

JavaScript error: jar:file:///home/xxx/.mozilla/firefox/xxx/extensions/[email protected]!/ext_bootstrap.js, line 70: TypeError: shouldReportError is not a function

Sorry for the delay here - are you still seeing this, and if so, can you supply STR?

No problems. I will test again and tell you.

Thanks!
