Features & Capabilities

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.

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

Is Session & Local Storage Copier Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Session & Local Storage Copier requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Session & Local Storage Copier is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
