Bug on pop-up default values

The pop-up of the extension has a bug. That is if you change the default values of pop-up, and then close and re-open it. It still opens with default values. It doesn't open with changed values.

Steps to reproduce:

1. Open the popup.
2. The enabled button is now on, just toggle it to off.
3. close the pop-up.
4. re-open the pop-up.
5. The extension functionality is now off, but the pop-up says it is enabled.

Edit: Do this all in a stack overflow questions page to better understand the enabling and disabling of extensions effect.

I appreciate all the effort in this extension. :)
