The Firefox add-on 'Toolbar Buttons' version 0.4.1.3 worked fine in both my desktop FF and Portable FF. The upgrade to version 0.4.1.4 works on my desktop but no longer with Portable FF. I get an 'Unexpected Installation Error' and FF's Error Console shows:
Error: e.location.getItemLocation(e.id) has no properties
Source File: file:///F:/PortableApps/FirefoxPortable/App/firefox/components/nsExtensionManager.js
Line: 4141
Can anyone help please?
