Inspect Locker

Inspect Locker saves a sanitized snapshot of the current page locally, so refresh shows the same locked state. It is built for Opera GX and other Chromium-based browsers.

Quick Start

1. Open opera://extensions.
2. Turn on Developer Mode.
3. Click Load unpacked and choose this folder.
4. Open any website, click the extension, and choose Lock This Page State.

Usage

• Refresh the page to restore the locked snapshot.
• Use Unlock & Reset in the popup to return to the live page.
• Internal pages such as opera:// and chrome:// are not supported.
