mystorage

A cross-site key-value storage accessible from the console.

mystorage is a powerful developer tool that provides cross-website key-value storage accessible from any browser console. Unlike localStorage which is limited to a single domain, mystorage lets you store and retrieve data across all your tabs and websites. Why you should install mystorage: Store data once, access it everywhere. No more copying tokens between tabs, no more losing temporary notes when you close a page, no more setting up complex backends just to share data between your local development environments.
