Browser extension

Know when a site is running Open edX.

Open edX Detector checks the active page for the openedx-release-line meta tag and shows the detected release line from your browser toolbar.

What the extension does

The extension is intentionally small: it detects one Open edX signal, updates the toolbar icon, and shows the result in a simple popup.

Detects Open edX metadata

Looks for <meta name="openedx-release-line" content="..."> on pages you visit.

Shows the release line

Displays the current domain and detected release line in the extension popup.

Changes the toolbar state

Uses the default icon when Open edX is not found and a green detected icon when the meta tag is present.

How it works

1

The content script scans the page

It checks the document for the openedx-release-line meta tag after the page loads and when matching head metadata changes.

2

The background script stores tab state

The detected result is kept in memory for the current browser tab so the toolbar and popup can show the right status.

3

The popup presents the result

Open the extension popup to see whether Open edX was detected and which release line was reported by the page.

Privacy first

Open edX Detector does not collect, sell, transmit, or persistently store personal data. Detection happens locally in your browser. Read the full privacy policy.
