Inspect the local data of the JS Port

[jsfan3]

All of the simulator's local data is located in the .cn1 folder within my home directory. Since I save it as JSON, this allows me to easily inspect the data.

I would like to inspect the data from the same application using the JS Port. However, the problem is that all the entries in Firefox Storage are empty. Why? Where is the data?

The data is being stored, though. I expected to find it in the cookies, but there are none.

Here is a screenshot:

It's in the index db under key/value. Warning, crashed my browser when I inspected it.
