Frequently Asked Questions (FAQ)

General Questions

What is LocalStorage Viewer?

LocalStorage Viewer is a Chrome extension that allows you to view and inspect the localStorage contents of any webpage in real-time.

Is it safe to use?

Yes, the extension is completely safe to use. It only reads localStorage data when explicitly requested and operates entirely within your browser. No data is transmitted to external servers.

Does it work in Incognito mode?

Yes, the extension works in Incognito mode with a "split" mode configuration, meaning it has to be explicitly allowed in Incognito mode through Chrome's extension settings.

Features

Can I modify localStorage values?

Currently, the extension is read-only. This is by design to prevent accidental modifications to website data.

Why do I need to grant permissions?

The extension requires minimal permissions to function:

  • activeTab: To access the current tab's localStorage
  • scripting: To execute the code that reads localStorage
  • sidePanel: To show the side panel interface
  • storage: To save your theme preference

Can I export localStorage data?

You can copy individual values using the copy button next to each item. Full export functionality is planned for future releases.

Troubleshooting

The extension icon is grayed out

This typically means you're on a page where the extension cannot access localStorage, such as Chrome's internal pages or extension pages.

I can't see any data

Make sure:

  1. The page you're viewing has localStorage data
  2. You've granted the necessary permissions
  3. You're not on a restricted page (like chrome:// URLs)

The JSON view isn't working

If a value appears as a string instead of a formatted JSON tree, it means the value isn't valid JSON. The extension only formats valid JSON data.

Technical Questions
