Where do the maps store with firefox?

Hello, i wanted to open this topic to ask if somebody knows where do the maps save files are stored. I use firefox and though that the other post called "How to transfer maps across computers" would help but it didnt, i asked there but i didnt got any answer so, can somebody help me?

I think in Firefox, you'll need to install a plugin that allows you to view and edit localStorage, which is where the maps are saved.
