问题
As per my previous post, I was referred to create a new post. As seen in the comments, there is a trail of progression for the issue, I'll rephrase here in this post:
I'm using a TamperMonkey script in FireFox.
I'm trying to persist a Dexie object/database into TamperMonkey's local storage with GM.setValue('unique-dexie-db-name', dexieDBvariable);
However when I go to retrieve this value (ex. I store this on google.com, and retrieve this on yahoo.com) with var dexieDB = GM.getValue('unique-dexie-db-name'); My returned object value is not a Dexie database object, but rather something else I can't use as a database.
My question: I'm unsure, but I think when storing this Dexie Database into TamperMonkey, it gets stored as a string, and, I should try to somehow JSON.stringify() the object fully in order to be able to reproduce and re-create it when I need it in the GM.getValue() call. How do I store this Javascript object as a string in order to be able to retrieve the value again as a whole later?
This is my working example code;

(second link looks better formatted in browser)
And, as stated before, I've tried playing around with JSON.parse() / JSON.stringify() but I'm not sure this is the path to go down.
