[Vite/Storybook.v7] Addon 'storybook-dark-mode' not working on FIREFOX

Hello,

I'm trying to use this addon to toggle my mantine color scheme along with storybook mode. However, when I set the 'storybook-dark-mode' addon in main.ts :

// main.ts
addons: [
        '@storybook/addon-essentials',
        '@storybook/addon-styling',
        'storybook-dark-mode',
],

and launch my app in Mozilla Firefox, my application crashes whenever I manually reload the page. Plus, even on the first load, I can't see the toggle button in the toolbar.

Here is the devtools console error:

Uncaught TypeError: j.localStorage.getItem is not a function

I'm using Chrome as a workaround but it is annoying for me because Mozilla Firefox is the main browser in my company.
