## Description

Session & Local Storage Copier lets you copy the entire sessionStorage or localStorage from any web page and paste it into another tab — even in a completely different browser or user profile.

How It Works:
The extension uses the system clipboard as the transport layer. This means data is not locked inside a single browser — you can copy storage in Chrome and paste it in Firefox, or move it between separate browser profiles.
<ol><li>Open the page you want to copy storage from</li><li>Click the extension icon, then press Copy (for sessionStorage or localStorage)</li><li>Switch to the target tab, page, browser, or profile</li><li>Click the extension icon, then press Paste</li></ol>
Key Features:
- Cross-browser transfer — copy in one browser, paste in another
- Cross-profile transfer — move session state between different browser profiles
- Supports both sessionStorage and localStorage
- Data validation — clipboard content is verified before restoring
- No external servers — everything stays on your machine

Use Cases:
- Transfer login sessions between dev and staging environments
- Move application state across browser profiles during testing
- Share session data between team members (copy, send via chat, paste)
- Quick backup and restore of localStorage during debugging
