Use the Chrome Extension for non-public webpages

When a webpage is not publicly accessible, you run probes using the Uiprobe Chrome Extension.

This guide assumes the extension is already installed.
If not, see How to install the Chrome Extension.

When to use the Chrome Extension

Use the Chrome Extension if the webpage you want to compare:

• requires authentication
• is hosted on staging or an internal environment
• is not accessible via a public URL

For public webpages, probes can be created directly from the web app.

Run a probe from the Chrome Extension

1. Open the webpage you want to compare in Chrome.
   Make sure the page is fully loaded and shows the state you want to validate.
2. Click the Uiprobe Chrome Extension icon in the browser toolbar.
3. In the extension popup, choose Run probe on this page.
   The extension uses the currently active tab as the webpage source.
4. Enter the Figma frame URL for the design you want to compare.
5. Start the probe.

The extension captures the webpage from your current browser session and sends it to Uiprobe for comparison.

What happens next

After the probe is started:

• Uiprobe creates or updates the probe
• a new probe version is generated
• results open automatically in the Probe Inspector

From this point on, reviewing results works the same as for any other probe.

Important to know

• The probe captures the current page state
  (logged-in user, feature flags, visible content).
• Re-running the probe later captures the page again and creates a new version.
• The Chrome Extension does not change how probes, issues, or versions behave.
  It only enables access to webpages Uiprobe cannot reach directly.
