Can't save settings on custom widgets

Can you look at your JavaScript console and let me know if there is an error being output?

Why not you create a custom widget and test it?
For me it says NS_ERROR_FAILURE
I don’t know what it means

Error: NS_ERROR_FAILURE:

I’m having a similar issue with all of the custom widgets classes I created. It does not let me save any data to the widget instances. Did something change in the way you are suppose to create your custom widgets?

I just did some more testing and it seems to be a browser issue. I’m running OS X 10.6.8 and it worked in FireFox & Safari, but not in Chrome or Opera.

I am using Windows 7, not working in Firefox, Chrome and IE 11.

I installed WP 3.9 beta where the plugin is integrated and there for works, the plugin is deactivated.
