Session & Local Storage Copier 作者： Yahor

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.

1. Open the page you want to copy storage from
2. Click the extension icon, then press Copy (for sessionStorage or localStorage)
3. Switch to the target tab, page, browser, or profile
4. Click the extension icon, then press Paste

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
