Risk Level

Trust Factors:

- The extension has a decent number of users (20,000) and a relatively high rating (4.6/5), which suggests it is a legitimate and useful tool.

- The developer information is provided, which adds some transparency.

Concerns:

- The extension requests several permissions that may not be necessary for its stated purpose of measuring web elements, such as activeTab, contextMenus, and storage.

- The content script has access to a third-party domain (https://extensionpay.com/*), which could potentially be used for tracking or injecting unwanted content.

Recommendations:

- Review the extension's privacy policy and terms of service to understand how user data is handled and what the third-party domain is used for.

- Consider running the extension in a separate Chrome profile or an incognito window to isolate it from your main browsing session.

- Monitor the extension's behavior and network activity for any suspicious activity.

- If you don't need the extension's full functionality, consider disabling or removing unnecessary permissions through the Chrome extensions manager.
