## Description

LocalStorage Editor adds a toolbar button to view and modify the localStorage and sessionStorage for the current tab. Open the storage editor to filter, search, copy, export, modify, add and import items, and to sync or discard changes as needed.

It uses permissions including storage, clipboardRead, clipboardWrite, and <all_urls> to inject a small content-script that acts as a proxy between the UI and the page storage. Quick select-all enables exporting or copying all items, while leaving items unselected helps you modify and sync only a subset.
